I have one that popped straight into my mind when reading your question. I was at film school, on one of my first films I ever did sound on. We shot a little film set in a skate park. I recorded a skateboarder costingcoasting along slowly from left to right. It sounded very similar to a distant airplane. And with a tiny bit of processing, that's how I got my first clean-ish recording of an airplane. This layer came in handy many times to build backgrounds or as a narrative tool.
This was almost 10 years ago, and was recorded on a mini-diskMinidisc. I wish I still had that recording.
