CDI: The explosion was heard over a radius of 25 miles and made a crater 25 feet deep and 200 feet square. The B-50 was an improved derivative of the B-29 with the same general appearance. It was operational from 1948-1953 and 370 were built.
The Cincinnati Enquirer wrote that thousands of locals turned out to see what had happened in the crash and provided conflicting reports from witnesses about the state of the plane as it nosed down. Some reported that the plane simply seemed to crash into the ground for no reason while others stated that the plane was already on fire and had failing engines before it hit the ground.
