L-1011 and Pegasus tour at Vandenberg

A day before the L-1011 carrier aircraft will depart Vandenberg Air Force Base to ferry the Orbital Sciences air-launched Pegasus rocket and its NASA X-ray space telescope to the Kwajalein Atoll in the Pacific, reporters got a tour of the jet and rocket at the "hot pad" staging area adjacent to the runway.

This will be the 41st flight of the winged Pegasus.

The L-1011 will carry Pegasus to 39,000 feet at Mach 0.8 for its launch.

Pegasus was assembled and fitted with its payload in Orbital's facilities at Vandenberg.

The 51,000-pound rocket is secured to the aircraft by five hooks.

Come aboard the aircraft for a tour!

The carrier jet has been launching Pegasus rockets for 18 years.

This will be the L-1011's first mission new, fuel-efficient engines.
