This Boeing 747 Flies With A 4.5m Door Wide Open

This is Sofia. Like the Italian actress, it will turn heads everywhere it flies. Not because of its cleavage, but because this Boeing 747 has a 4.5m by 4.2m door on it, which opens to reveal a 2.5m telescope.

The Stratospheric Observatory for Infrared Astronomy - which went through $US500 million in modifications after two decades of engineering - has finally been tested after its construction, flying at 15,000 feet (4500m) and 415km/h with the door fully open. The test was a complete success, and in 2010 they will start testing the telescope itself. [Flight Global]
