V-22 Osprey Plane crash
11 June 1991
A Boeing V-22 Osprey prototype crashing during testing in Wilmington, Delaware back in 1991. This was its demonstration flight at the Boeing helicopter flight test centre.
The cause was problems with the gyro wiring which lead to craft being very badly damaged.
The two crew members received only minor injuries.
The V-11 has been had a number of issues and accidents in its past claiming 30 lives. But its unique usefulness of its multi-mission design with its vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) has kept it in production and is still used today, even in Iraq.
Today, several 100 of these have been built for US military costing around $100m each. Equipped with glass cockpit, four Multi-Function Displays, full fly-by-wire computer controlled triple-redundant flight control systems.
