High Altitude Research

In continuing its program for investigating flight at high altitudes, the Air Corps ordered from Lockheed a twin-engine airplane designated the XC-35. This was the world's first airplane specifically constructed with a pressure cabin. For its achievements with the XC-35 in high-altitude research, the Air Corps was awarded the Collier Trophy for 1937.
