The Blackbird is the X-Men's main source of conventional transportation. Professor Charles Xavier somehow gained at least one working version of the RS-150 Blackbird from S.H.I.E.L.D., After the X-Men's Stratojet had been destroyed by Count Nefaria. Located in an aircraft hanger on the grounds of the Xavier's School for Gifted Youngsters, the Blackbird served the Professor and X-Men for many years. At some time, the Professor upgraded to the SR-71 Blackbird. Devil's Rock was the exit and entry point for the X-Men's aircraft. After the X-Men were thought dead in Dallas, Texas, Nightcrawler, who had since joined Excalibur, teleported into the Skunk Works, a part of the Lockheed Aircraft Corporation, and started-up the SR-71 Blackbird, taking it back to England.
After an extended sojourn in space with the Starjammers, Professor Xavier returned to Earth and both the original and third teams of X-Men reassembled under his leadership. At this time, Prof. Xavier asked Forge, a mutant with an unusual talent for inventing mechanical devices, to upgrade the Blackbird and include Shi'ar technology, including a cloaking device which literally made the Blackbird invisible. The Professor also had Cerebro's, the X-Men's original machine used to detect mutants all over the world, software installed into the Blackbird, for non-telepathic use. Professor Xavier later had many Blackbirds built and filled the hangar. After deciding that he needed to make a stronger presence, Professor Xavier regathered his X-Men as a public team and created the X-Corp. Professor X had new Blackbirds designed, ones with an "X" across the top of the jet. As Cerebro had become sentient and destroyed, Beast added Cerebra, Cerebro's more powerful replacement, to the Blackbirds.
After Kuan-Yin Xorn impersonated Magneto and destroyed the mansion, Beast rebuilt the sub-basement and Cyclops asked Angel to purchase new Blackbirds. Since the mansion's reconstruction, the exit and entry point for the X-Men's aircraft was relocated beneath the basketball court. Upon departure and landing, a klaxon will sound warning for anyone nearby to vacate the area. Students are advised to move immediately, once the klaxon sounds. Even after moving to Graymalkin Industries and later Utopia, these new Blackbirds have moved with the X-Men.
