The aircraft is widely regarded as the most difficult aircraft in the world to fly. U-2 aiframes are used to perfrom intelligence, surveillance and reconnaissance at altitude's more than 70,000 ft. For pilots to fly at such extreme altitude's they are required to wear full pressure suits similar to what astronauts wear. These full pressure suits require extensive maintenance provided by the 9th Physiological Support Squadron. Before flight pilots undergo a rigourous schedule to ensure themselves and their suits are mission ready. To view slideshow.
