I was outside cleaning up the Rat Race, I heard the whistle and then the roar, I knew it was going to be special but was it a radial engine or a Merlin? Good news, it was both. There was a P51 Mustang, a Corsair and I think, a T6 flying formation and doing fly-bys at the local airport. They did a couple fly-bys and headed northeast.
Earlier in the day I heard radial engines, assuming it was the local Stearman that frequent Galesburg. It brings tears to my eyes thinking about the Heroes that flew these machines in WW2.
Some people think the whistle is from the gun barrels, this bird can whistle without them. Apparently, they were here for a bit, this was on a friends facebook, he works at the airport from time to time. Semi-retired.
Apologies to anyone that can't see it.
