NASA possesses a modified Boeing 747 SP known as SOFIA – the Stratospheric Observatory for Infrared Astronomy – which packs a 2.5 meter telescope. When SOFIA reaches its working altitude of between 39,000 and 45,000 feet above sea level, above most of the clouds and water vapour in the atmosphere, the 'scope can capture data that's hard to get on the ground. To do so, SOFIA opens a special door in the rear of its fuselage so the instrument doesn't have to peer through the plane's skin.
