The first Pegasus launch to use Stargazer was conducted on June 27, 1994, as the maiden flight of the Pegasus-XL. Previous launches used the NASA-operated Boeing B-52 nicknamed "Balls 8," which was also used for four subsequent launches, as the original Pegasus could not be launched from Stargazer due to clearance issues. A modified version ...
After an Airbus A350 production increase, Airbus aimed to deliver 880 aircraft in 2019, and raise A320neo output to 63 per month by 2021; the Beluga XL fleet was expanded with a sixth aircraft in June 2019. [10] The BelugaSTs could still have 10–20 years' flying life left, and may be offered for sale, or used to serve external customers. [10]
The IBEX satellite was mated to its Pegasus XL launch vehicle at Vandenberg Air Force Base, California, and the combined vehicle was then suspended below the Lockheed L-1011 Stargazer mother airplane and flown to Kwajalein Atoll in the central Pacific Ocean.
