I'm working on a personal mission history of a 445th Bomb Group flight engineer for his grandson. The family has provided a personal log of his missions and his account of the 4 Apr 45 attack on the Me 262 airfield at Perleberg, Germany has a wealth of details. On bomb run, an 88mm round goes through the port wing and knocks down the left main gear. The engineer is concerned about a hole in the left wing tanks, so he goes to check the fuel level in the wing tank. I'm trying to get a visualization of where the sight glasses would be located in the B-24. I don't want to wait until the Collings Foundation B-24 comes to AZ in April.
