Fuel leaks in aircraft can be a serious threat. After all, without fuel, the aircraft cannot fly and becomes one huge glider. Following a suspected fuel leak on Monday a British Airways Boeing 777 was forced to divert to St John’s midway through its transatlantic journey. Thankfully, the aircraft made its diversion safely without further incident.

The flight doesn’t operate daily. Instead, it’s is scheduled to depart Heathrow on Monday, Thursday, Friday, and Sunday.

What about Monday’s flight?

On Monday BA 253 didn’t make it to Nassau. Midway through its transatlantic crossing, the aircraft had to divert to St John’s. The pilots believed that the aircraft had a fuel leak. As is always the best course of action, the pilots decided to adopt the safe rather than sorry school of thought.

The aircraft turned towards St John’s midway across the Atlantic as the airport would’ve been the closest diversion airport to the aircraft at the time. According to data from, the aircraft touched down in St John’s at 16:41 UTC, around six and half hours after taking off from London Heathrow Airport. According to the Av Herald, the aircraft landed around 100 minutes after the fuel leak was first suspected.

St John’s Rescue

The Av Herald reported that, upon arrival in St John’s, the pilots of the Boeing 777 requested that emergency services check the aircraft for fuel leaks. However, it is unclear what was found upon arrival. According to data the Boeing 777-200, registered as G-YMMU, is still on the ground in Canada.

The next day a replacement Boeing 777 (G-YMMA) flew to St John’s to pick up the stranded passengers to continue their journey to Nassau, before continuing to George Town. It arrived in George Town at 23:16 on the 5th of November.
