Around the summer of 1991/1992 or so, my father was teaching a summer semester at St. Andrews in Scotland so decided to fly his family out to meet him. I was a kid.

I believe the flight would have been on UAL, Air France, or BA and we may have had a stop-over in Canada - Our final destination was LHR. I *think* this would have been on a 747, or something similar - we were in Economy and flying on UAL miles, for sure.

Over the North Atlantic, after a possible stopover (can't remember, too young), the cabin depressurized, and we had to execute a rapid decent and return to either Montreal or Quebec very quickly. No injuries that I know of, but I recall that it was quite alarming for the adults - I was mostly staring at the projectors that came down, showing a sunset (memory is fuzzy), and not all of the air masks worked so cabin stewards were passing out portable oxygen containers. I mostly remember it being loud.

We landed at the airport quite late (I remember being hungry and nothing was open), and my father was awoken via phone call in the middle of the night in the UK saying there was an issue with the flight. When we arrived, he was pretty visibly shaken.

We were later placed on an alternative flight to LHR, which arrived without issue.

Try as I might, I can't find the flight details, but on the return flight we were upgraded to Business Class on the upper deck of a 747, which was cool.

Is anyone able to provide further details?
