Sure, I've got two.
This was about 20 years ago. I was flying commercial from LaGuardia to London and right at the point of rotation one of the left engines exploded. (Where's the crash position avatar?) I was at the window on the right side so I couldn't see the engine. My first thought was a tire blowout, but that thought only lasted a second, beacause all the passengers on the left side could see the fire and were not happy. The pilot was screeching the plane to a halt and I was becoming increasingly concerned about the water ahead of us. Someone got on the PA and was clearly very shaken, they said the fire was out and we would have to stay on the runway while the brakes cooled. There was concern that the brakes had fused and we would not be able to taxi back. So three hours we taxied back to the terminal where we were shuffled from one plane directly to the other, because we were technically out of the country.
Next...
This one was almost 25 years ago. On a flight back from London, we landed in Gander Canada for fuel. No problems so far, but they could not get the plane to restart. We ended up staying in the airport for 13 hours, which at the time was nothing more than a gas station. A plane had to be brought in from Boston, and crew from elsewhere. They quickly ran out of coffee and only had the blankets and pillows from the aircraft.
You would think I would be leary of flying as a result of these, but I'm not.
BTW if anyone can find the NTSB reports for either of these, please let me know. I'd love to read them, I've never been able to find them.
