Portland Airport, Maine – August 30, 1941
At 1:45 p.m., on August 30, 1941, a U.S. Army O-52 observation plane (Ser. No. 40-2705), was making a landing at Portland Airport, on the north-south runway. Just as the plane was about to touch down, a civilian plane crossed its path from the east-west runway and a collision between the two occurred.
The O-52 was wrecked, but the pilot and his passenger escaped with minor injuries. The two civilians aboard the other aircraft were uninjured.
The O-52 was assigned to the 152nd Observation Squadron.
