Greg, I don't know if you have ever seen this feat before. I was at Whiteman AFB (Wings Over Whiteman Air Show) on Saturday at the airshow and they perform a "Heritage Flight"

This amazing feat to shows a A-10, P-51 and a F-15 fly together in formation.

The P-51 has to be at full throttle while the A-10 and the F-15 are flying as slow as possible.
