Well if the topic is serendipitous encounters with warbirds here’s mine: I was driving back home onto base near sunset and was annoyed at getting stopped at a stoplight. Then I heard something beautiful. Wow, that sounds like a Merlin.* Sure enough a Spit XIV flies right across the road directly in front of me at an altitude that was probably illegal. He was even banking slightly towards me in a turn towards the runway. He was heading for the base field for an air show that weekend. A truly beautiful sight and so weird to see it while sitting in traffic.
The next morning I was mowing my lawn and suddenly a TBM flew over on its way to the same air show. That was decidedly NOT a beautiful sound or beautiful airplane. It sounded like a couple dozen angry lawn mowers all out of sync and what a big ugly thing it was.
*Yeah… OK, it’s a Griffin not a Merlin.
