Two British Airways (BA) Concordes developed problems during recent transatlantic flights, the airline revealed Wednesday.
An engine failure forced one New York-bound plane to turn back to London and another flight was forced to cut its speed when cracks appeared in a window, the airline said.
The engine fault was discovered during a flight on Sunday, whena cockpit warning light came on. The faulty engine was turned off and the plane, which was carrying 82 passengers, flew back to Heathrow on its three remaining engines.
The window cracks were found during a flight last Wednesday, Oct. 30. Although the plane was forced to slow down and arrived inLondon 40 minutes late, BA said the fractures were "tiny" and wereon the outer layers of a cabin window.
Air France has begun an inquiry into the engine trouble which hit its Concorde flight, according to a BBC report.
Thursday marks the first anniversary of the return of Concorde passenger services, following the deaths of 113 people when one ofthe Air France planes crashed near Paris in July 2000.
