Before I forget the details from that special day, I wanted to point out:
- How difficult it is to identify aircraft from underneath them. You don't think about it; but all the images you see are always from at, or slightly above, their flight level. Some are distinctive, sure, but quite a few blur together when seen passing directly overhead.
- The P-51's were FAST. If I recall correctly it was a flight of three and, even from a distance, you could see that they were moving a good 30%-40% faster than anything else flying that day (or at least it sure seemed like it). That was great.
