Birds in Cages


Airplane hangars have an interesting effect. They seem to diminish the achievement of flight. An airplane in a hangar seems out of place when you consider that its function is to travel thousands of feet above earth at speeds faster than any creature in nature. From time to time I look at a familiar plane in a hangar and think of all of the adventures it has carried me through; early morning sunrises at 11,000 feet, moonlit flights low over silvery breakers just off the beach, wheeling down over canyon rims in redrock country, soaring over snow-capped peaks that would take days to climb, darting around cumulus canyons, spectacular evening air-to-air photo flights. All of these glorious moments were happening at over 100 miles per hour suspended in the sky by nothing but air pressure differential, often bathed triumphantly in sunlight. Any object in such a position should surely meet its end in a mass of twisted metal, yet here it sits, pristine, with a roof overhead underneath the same fluorescent lights that most people labor under grudgingly. Airplanes in a hangar give the impression of machines of potential, but aside from a few bugs on the wings and worn tires, they show virtually no sign of their past journeys through previously unattainable dimensions. An airplane wreck gives the undeniable impression that the machine was at one point careening through space. Airplanes resting quietly indoors show no such evidence. The most brilliant minds of men designed these masterpieces. Some of man's keenest reflexes are needed to fly them precisely. Buildings constructed by the modest labors of men house them anonymously.

Shutterspeed: Piper Comanche

People often ask me questions about how I compose air-to-air photos such as these. The Shutterspeed blog is meant to give some insights into the world of air-to-air photography. There is much more that goes into one of these flights than I could touch on here, but hopefully this will give an idea of some of the elements in creating these images.


Most of my time in the air has been in slow taildraggers. I learned to fly in a Citabria and I've been flying the Champ for seven years. Sure, I've spent plenty of time in Cessnas. As most pilots are, I'm familiar with the 172. I've gotten to know the 182 to a lesser extent. I've had stick time in RV's, but by and large, I'm accustomed to going slow. I've taken several multi-state cross-country flights in the Champ and they often aren't much faster than driving, though they're always an adventure. When the opportunity came to train for my commercial license in a Piper Comanche 250, I jumped on it, even though I didn't fully understand what a gem of an airplane I was about to be introduced to. I'd flown Cherokees in the past. The Comanche has the same basic shape as a Cherokee and as both aircraft are Pipers, I assumed the Comanche would handle and fly a bit like its newer brethren. I couldn't have been more wrong. The Cherokee family are generally stable, easy to fly airplanes, but I've never found them to be all that inspiring. The Comanche soars in comparison.

Confident

Charlie is my flight instructor. He taught me while I was pursuing my commercial license and he continues to teach me as I work toward my flight instructor certification. He's been flying this particular Comanche longer than I've been alive and is undeniably a master of the aircraft. Today, Mark would be flying me in the L-5 once again. Mark, Charlie, and I are all close and we've flown one other photo flight with Charlies Cessna.

Charlie has allowed me use of the Comanche from time to time and it is a true freedom machine. Each takeoff is more like a launch than a departure. I've loaded four people in the plane and taken off with near full fuel and its performance doesn't cease to inspire. I never thought I'd love a metal nose-wheel airplane like the Comanche, so when it came time to shoot it air-to-air, I wanted to do it right. I'm always looking for new aspects in my photography. I try to inject variety in each photo flight. I decided that the softer light of evening would compliment the powder-blue Comanche better than the more harsh light of morning. While the air over the foothills can often be rougher than the plains on a summer evening, we'd had a good stretch of clear, calm weather and I wanted to try their offerings of scenic backgrounds late in the day for a change. Shooting in the evenings has several advantages, not the least of which is that there is not a 3:08 wake-up. I drove to the airport after work and Charlie and Mark and I did some casual hangar flying as we waited for the sun to get lower. We pulled the planes out, but Mark and I departed first and headed east to do some quick aerials for a friend. Charlie and his wife Kathie departed in the Comanche and we met on the ground at Longmont. We knew flying in formation with dissimilar aircraft like the swift Comanche and the sedate Stinson would be a challenge, especially for Charlie. We briefed the flight as always and then started engines and taxied out for departure.

Once in the air, I dropped the windows and ran a took a few test shots. Mark guided us over toward the hogback ridges as Charlie maneuvered into position. The Comanche's three-bladed prop makes for a great speed brake when in low pitch, so it was relatively easy for Charlie to match our speed. We flew level along the hogbacks to establish our speeds and positions while still providing some interesting scenery for backdrops. I'd never seen the Comanche in the air and it is an absolute stunner. I've always found its angular lines, clean profile, and slender tapering of the fuselage to be reminiscent of a shark. Up here in the air, it seemed to glide as effortlessly as a mako through the deep. There was plenty of effort involved, however. Mark was positioning Charlie just so and we began a series of inside and outside turns and headed over a reservoir for some water backgrounds. Between the low power settings for the Comanche and the slight turbulence (a little goes a long way) Charlie was working hard. Mark was contending with a familiar area but unfamiliar lighting. The images are a picture of luxury; a couple flying their powerful airplane over the mountains, perhaps to a weekend getaway. In reality, I was hearing the gear horn squawking at times in the background when Charlie would make a radio transmission. Kathie was more concerned with the proximity to the rocks than what would be on the menu at the Chateau.

Flying along the ridges

I'd told Mark in the past not to spend much time over residential areas as they can ruin an otherwise perfect photo. I noticed through my viewfinder that we were over the town of Lyons. I mentioned the fact to him and asked if there was a better prospect for scenery nearby. "Hold on, this is gonna be worth it. Be ready for it." I didn't know what he might be referring to, but I took his word for it, not taking my glance off of my subject. In a few seconds, he began a right turn and we came around the corner of a dramatic sandstone ridge. Charlie was positioned perfectly as Mark put the ridge between the Comanche and the town of Lyons. In the brilliant evening light, the ridge was lit up like the redrock country of eastern Utah and the light blue of the airplane made for a spectacular contrast. We'd flown by the same location on previous morning flights when the entire area was in the shadow. It's amazing how one area can take on such vastly different characteristics with the light coming from the opposite direction.

The "around the corner" shot

As the sun got lower, we gained some altitude and tried several sun-blocking silhouettes, one of the more challenging tasks of a photo flight. We also did some distance shots, placing the Comanche further away from us and putting much more sky in the picture. In a steep bank a few hundred yards out, the profile of the Comanche looked even more aggressive and shark-like.

Mako Shark

When there was not enough light left to work with, we headed home. Charlie broke formation and powered up. As if propelled by a few quick thrusts of its tail, the Comanche sped past us and and vanished to the east as a full moon was rising. Now released from leading the flight, Mark performed several maneuvers that expressed his joy of flying the Stinson. Such acts are always thrilling when facing rearward.

Yes, the Comanche will always be a favorite. It is not the newest, fastest, or most complicated airplane out there. It is a beautiful and competent performer. Its understated manner may fool many into thinking it nothing more than a Cherokee, but the Comanche remains a benchmark among light aircraft. We've had some remarkable and memorable flights together and it was a joy to compose this photo flight.

Shutterspeed: AT-6 Texan

People often ask me questions about how I compose air-to-air photos such as these. The Shutterspeed blog is meant to give some insights into the world of air-to-air photography. There is much more that goes into one of these flights than I could touch on here, but hopefully this will give an idea of some of the elements in creating these images.



I had been working in the field for eleven days straight, getting up before dawn every day. On my four precious days off I had lots of sleeping late scheduled. So why was my alarm clock going off at 3:22 am? One reason is that I can never bring myself to set an alarm clock to a multiple of 15. The other is that I'd gotten the call the previous afternoon that we were going to shoot a T-6 in the morning. I've always loved the North American T-6 and SNJ (Navy version). In addition to being beautiful, loud, exciting warbirds, my grandfather flew them in the Navy and had his very own issued to him while he was Commanding Officer of NAF Cabaniss Field in Corpus Christi, Texas. He has always had nothing but the highest praise for this advanced trainer.

I stepped outside into the darkness and scanned what sky I could see. There was a very high and very thin broken layer. The moon was behind the layer, but was shinning through. I was concerned that there could be heavier clouds to the east, blocking direct sunlight.

Mark and I arrived at the airport just as the very slightest hint of the coming dawn could be detected to the northeast. It did look as though there was a substantial overcast covering part of the sky in that direction, but the sky was clear and starry to the north. To the south, the lights of Denver reflected off the broken layer which had now become more of an overcast. "Take what we can get" was the thought of the morning.

Over in the corner of the flourescently lit hangar, Mark was pre-flighting his L-5. I've worked with Mark more than any other photo pilot and his big green Stinson is my preferred photoship. He was busy taking out the rear seat and reversing it. The L-5's rear position has windows which open on both sides and I couldn't think of a more ideal way to shoot an airplane than facing backwards in this plane with open air on both sides. I opened the hangar door and began pulling airplanes out so that we could get the L-5 out. It was still very dark out as we mounted up. By the glow of the cockpit light, Mark ran through the checklist that would bring the L-5's engine to life. He hit the starter and the big Lycoming began to cough. With both of my windows open, I could hear the individual unmuffled pops of each cylinder from the twin exhaust stacks on either side of the airplane as Mark coaxed the engine out of its dormancy. We taxied out in the twilight. As we approached the runway, I reached around to the push-to-talk switch by the rear throttle and tapped it seven times, queuing the runway lights. After the run-up, Mark taxied into position and added power. As we accelerated, the runway lights began appearing to each side of my vision, racing back behind us. A takeoff facing rearward is a pleasantly unusual situation every time.


Mark flying the L-5

Once aloft, we flew a graceful circle around our friend Charlie's place. His cows were bedded down in the pasture. The kitchen light was on. It's not every day you beat a cow man out of the house, but we were already airborne while he was cooking eggs. Heading west toward our staging airport at Longmont and climbing, I studied the cloud cover. It looked as though the sun might be partially obscured as it rose, but the sky seemed to be clearing slightly and the cover moving south. A golden glow was now radiating off of some of the furthest clouds. We'll pull this off, I thought. I gazed at the twinkling lights of houses and small towns below. Flying between dusk and daybreak is always a meditative affair. I leaned back, resting my head on the fire extinguisher and listened to the burbling of the engine. I said a quick prayer for good light, steady hands, and safe flying. A crackling in my headset awakened me from my stupor as Mark tuned in the Longmont AWOS frequency. Before long Mark was making radio calls and we descended into the empty pattern. Flying an arcing base-to-final, Mark set the big L-Bird onto the ground with authority.


View of an L-5 landing facing rearward

We walked around the ramp for a few minutes discussing the game-plan and studying how the light was beginning to hit the foothills. Just as the first rays of sun broke the horizon we heard thunder to the south. We swung our glances upward in unison and spotted the T-6 entering a base leg for runway 29. The gear wasn't down and the engine wasn't getting any quieter. The big plane roared down toward the threshold, leveled out about 20 feet over the runway and zoomed past us, then pulled up and dropped the gear and turned back inbound. The Pratt and Whitney chewed up the still morning's silence. After landing, the Texan taxied over to our end of the ramp and shut down. It was a beautiful machine on the ground. I couldn't wait to see what it would look like in flight. It was painted in a colorful post-war Navy SNJ scheme, but we later learned it was delivered to the Army Air Force in 1944 as an AT-6D. Doug emerged from the cockpit and greeted us. Doug and Mark both work at the same airline and got the idea for this photo shoot while flying together recently. Mark introduced me and we promptly began the briefing. Doug has been flying the T-6 regularly and was confident in its ability to fly safely with the slower L-5. We discussed our plan to get the silhouette shots first while the sun was the lowest with the most color. Then we'd proceed to a reservoir to get some deep blue backdrop on some inside orbits. We'd then move to the ridges and valleys of the foothills for some rocky and shadowy backdrops. We also would attempt an approach and landing sequence. After more details on the formation itself, we bumped fists and mounted our warbirds.

Comm checks on taxi and run-ups complete, Mark departed first and turned out to the north. Doug departed and turned toward us, doing s-turns as the L-5 climbed sedately into the brilliant morning air. Although Doug was still a bit far out, I began snapping a few images as he banked over the fields below us with his nose pointed nearly at our position. I've found that sometimes "free-style" shots where the subject is maneuvering can result in some keeper images even if there is a bit of distance. When we leveled off, I guided Doug into position so that he could put himself directly between the sun and our position. I'd say, "five feet forward... ten feet up..." and Mark would relay the instructions over the radio. When he finally blocked out the sun, he saw his shadow on our plane and knew to hold position.


T-6 Silhouette

We worked our way over to the lake and began a series of outside and inside orbits. I was very pleased at how expertly Doug was handling the formation, especially the inside turns which are always tricky for an airplane that is normally faster than the lead plane. On the inside turn, the inside plane must fly noticeably slower than the lead in order to maintain position. We were concerned about how well the T-6 would slow down from the L-5's already slow 110 mph max cruise. Doug handled it like a pro. Inside turns yield some of the more dramatic images. The plane is banked steeply over the background below it and there are usually good vectors and a sense of motion in the photos and they also highlight the terrain underneath. The lake was royal blue and the surface was glassy. It wasn't unspoiled, however, as some of our orbits brought a boat and wake-boarder into frame. While I commend the wake-boarder's tenacity to get up early to seek the calmest water possible, he simply didn't fit in an image of a 65 year old military plane. Fortunately, we were able to get plenty of good material without the recreational equipment featured, but some with the boat wake made for some interesting vectors.


Over water

After several orbits we decided to leave the lake, I'm sure much to the relief of those in some of the houses near the shore who were certainly awakened by the sound of the two warplanes. On our way to our next shooting area, we instructed Doug to perform some more free-style maneuvers while en-route. We flew up and down some of the north-south oriented hogbacks in the foothills. These layers of sediments were shoved out of the way millions of years ago as the core of the Rocky Mountains broke through the plains. Today they cast great shadows well into the morning on their west sides while the east flanks glow in the morning light. It is an area of contrasts and we positioned Doug over the shadows to take advantage of this contrast. The brightly colored plane glowed with warmth over the darkness below. After working that angle, I'd have him switch sides and compose images with the glowing rocks complimenting the T-6's stunning paintwork.

Over shadow

We performed a few more orbits with different angles and I was satisfied with the material we'd collected. Mark had been relaying most of my instructions to Doug, but I put the camera down and reached for the push-to-talk switch. "Alright Doug, solid work. I think we can head back to the airport now and try for a landing shot." His answer was positive, but his voice had a hint of relief. He'd clearly been working hard on this flight. "OK, guys. Sounds good. Let's do it."

Mark guided us toward Longmont. Doug extended the landing gear and followed us to a downwind. He and Mark coordinated the approach. We would position him on final, then Doug would stop flying off of us and concentrate on the approach while Mark held the L-5 in position above him. Shortly before touchdown, we'd initiate a go around, break formation and land. We flew a long final, giving me plenty of opportunities to slow the shutter speed down to give the background a touch of motion as the big North American flew lower and lower over it. In the viewfinder, I saw Doug cross the threshold as his shadow came into view and got closer and closer to meeting the main wheels. They never quite met as Doug called for the go-around, added power and began climbing back up toward our position, retracting the gear. After leveling off, we broke formation and landed separately.


Approach-to-landing

On the ground we were all grins, but did a debriefing discussion and looked over some of the raw photos on the camera. I don't think we've ever done a photo flight that went that smoothly. There were virtually no squawks or negative issues we could think of. The conditions could not have been more perfect and our team was rock solid in the air. We watched as Doug climbed back in the T-6, fired up the Pratt and Whitney once again and taxied for departure. I took photos of his departure and the subsequent high-speed pass. Mark and I climbed back in the L-5 and departed, reflecting on a near-perfect flight.
