The crew of a British Airways Boeing 747-400, registration G-BYGA performing flight BA-56 from Johannesburg (South Africa) to London Heathrow,EN (UK), decided to dump fuel and return to Johannesburg after two thrust reversers were indicated unlocked after takeoff. The airplane landed safely about 90 minutes after takeoff.

The flight was initially postponed by 23 hours and later cancelled.
