The only surviving aircraft of Gastello's flight, Lt. Vorobiev's bomber, returned to base sometime after 2 pm. The only known crewmen of the second bomber are lieutenant Vorobiev and his navigator lieutenant Rybas. They reported that after about an hour in the air, they located a large armored column on the highway near the village of Dekshany, and conducted a bombing run from 400 meters of altitude. Having expended his bomb load, Gastello then flew a low-level pass, with his defensive gunners firing their 12.7mm (.50 cal) machine-guns at enemy vehicles. Gastello's plane received a direct hit in the fuel tank and caught fire. Initially set on a return course, his burning bomber then turned around, headed back to the transport column, and dove straight in, causing a "powerful explosion that shook the gaggle of enemy armored vehicles, and caused a burning storm that engulfed other enemy tanks".
