My second flight ever. I was a high school senior on an Air France charter originating in PHL filled with high school kids. Half of us were going to London while the other half would then go on to Paris. As we approached London the captain got on the horn and first spoke French for what seemed like 10 minutes. He then switched to English and told us that due to "mechanical difficulties" we were going to skip London and go directly to Paris.

When we got to Paris we circled for around two hours, presumably to burn off fuel. We then made the most rapid descent of my life. It felt like my head was cracking open. The runway was lined by fire trucks and ambulances but we landed with no problems. We later learned that the landing gear had malfunctioned and they just got it down in time for us to land, else we'd have done a belly landing.

Afterward, they put us on a commuter flight to London, where I got to chat with some friendly, drunk British businessmen. It was a fun trip overall.
