The Spitfire should have been around 1,000 pounds lighter than the P-40, top speed peaking around 18,500 feet versus 15,000 feet for the P-40

The question is which P-40, the memo implies it was at Ottawa. Three plus hours at economic cruise Dayton to Ottawa, say 7 hours round trip? Buffalo to Ottawa is under half the distance. Buffalo to Dayton would be around 90 minutes at economic cruise.
