At 70,000ft and above, the “Dragon Lady” still has the stratosphere largely to itself, just as it did 65 years ago on its first flight. At these altitudes, the pilot is more astronaut than aviator. In the cocoon-like, pressurised cockpit of the U-2, wrapped in a bulky pressure suit with a large spherical helmet, the pilot breathes 100% oxygen. Some of the features of this kit can still be found on spacesuits in use today.
In air this thin the margins between living and dying are narrow. Indeed, the pilot faces the constant danger of hypoxia (lack of oxygen) and altitude-induced decompression sickness. Like any plane, the U-2 has to fly fast enough that the plane doesn’t stall and not so fast that the plane breaks up – the challenge for the U-2 pilot is that at 70,000ft there may be only a few miles an hour difference. An accidental nudge on the controls could spell disaster.
Close to the ground the plane’s mechanical controls, easy to manipulate at high altitude, now take muscle power. The U-2’s lightweight design makes the plane liable to float over runways, bounce back into the air if the landing is too hard and very sensitive to cross winds. The weight-saving bicycle-style landing gear makes it difficult – and hard work – to keep the plane in a straight line and its wings level as it slows down.
The visibility from the cockpit is so limited that when landing the pilot has to rely on instructions from another U-2 pilot driving a car that races on to the runway when the plane is coming in to land. These chase cars have reached speeds close to 140mph (224km/h).
“The U-2 really attracts the kind of pilots who want to say ‘I fly the most difficult aeroplane in the inventory’,” says Greg Birdsall, Lockheed Martin’s U-2 deputy programme manager. “They take a pilot candidate and put him in a trainer aircraft with a seasoned instructor pilot in the backseat to see how they take to the peculiar handling characteristics of the aeroplane.” Only around 10–15% of pilots who apply to join the programme are accepted.
