The Mystery of Pittsburgh's "Ghost Bomber" | History Center
Sixty years ago, at the height of our nation’s Cold War frenzy, an American military plane crashed into an icy Pittsburgh river, sparking one of our city’s most interesting – and enduring – unsolved mysteries.
On Jan. 31, 1956, Maj. William Dotson and five crew and passengers were flying over Pittsburgh on a routine training flight from
Nellis Air Force Base in Nevada to pick up a cargo of airplane parts at Olmstead Air Force Base in Harrisburg, Pa. During the cross-country flight, the plane refueled at Tinker Air Force Base in Oklahoma and again at Selfridge Air Force Base in Michigan.
At around 4 p.m. on Jan. 31, the crew reported a loss of fuel and requested permission to land at Greater Pittsburgh Airport. When Maj. Dotson realized their fuel wouldn’t last, he instead asked to land at Allegheny County Airport.
At 4:11 p.m., with his fuel supply completely empty, his engine malfunctioning, and without any available airstrips nearby, Dotson was forced to make a hasty decision.
As his B-25 Mitchell bomber glided silently over the Homestead High Level Bridge (today’s Homestead Grays Bridge), Dotson made a wheels-up splash landing into the Monongahela River near the Glenwood Bridge in Hays.
Conspiracy theories abound. Some suggest the bomber carried dangerous or mysterious cargo and that the U.S. military secretly recovered the plane’s wreckage immediately after the crash landing to hide its true contents.
Some believe the mystery bomber may have been carrying a nuclear weapon or even a UFO from Area 51 near Las Vegas.
Many believe the highly polluted Mon River corroded the aluminum exterior of the aircraft decades ago, only the steel engines and landing gear remaining.
Others cling to cover-up myths that range from the plane carrying Soviet agents to Las Vegas show girls destined to entertain senators in Washington, D.C.
