Proteus Performs Low-Level Fly By

EC02-0057-74
Proteus aircraft low-level flyby at Las Cruces Airport. The aircraft was designed to cruise at altitudes from 50,000 to more than 63,000 feet for up to 18 hours. Proteus’ small cabin was pressurized to allow the flight crew a shirt-sleeve environment equivalent to an altitude of 14,500 feet when the aircraft is at 55,000 feet, or 15,500 feet at a 60,000-foot altitude.March 15, 2002NASA Photo / Tom Tschida› Proteus Project Description
