A UIA Ukraine International Airlines Boeing 737-500, registration UR-GAT performing flight PS-146 from Brussels (Belgium) to Kiev (Ukraine), was cleared for takeoff runway 25R, tower advised the next arrival was 3nm out. The Boeing 737-500 however did not commence the takeoff roll.

A KLM Fokker 70, registration PH-KZU performing flight KL-1725 from Amsterdam (Netherlands) to Brussels (Belgium), was on short final to Brussels runway 25R.

About 20 seconds after the takeoff clearance tower queried the UIA crew advising the arrival was "pulling up". The crew still did not commence takeoff.

About 40 seconds after the takeoff clearance the UIA Boeing was finally accelerating for takeoff still at low speed, however, the separation between the Boeing 737-500 and the arriving Fokker 70 had become too tight, tower therefore radioed "UIA 146, stop immediately, I say again, stop immediately". However, the crew continued the takeoff run without response on the radio.

About 8 seconds later Tower instructed again "UIA 146, hold position immediately!", however, no response on the radio, the aircraft continued the takeoff run.

Tower now instructed the arriving Fokker to go around and do an immediate turn to heading 010, which the crew complied with initiating the go-around at about 700 feet MSL.

About 2:20 minutes after the takeoff clearance tower handed the Boeing 737-500 off to departure, this time the crew acknowledged promptly and switched to departure.

The Boeing 737-500 continued to Kiev for a safe landing. The Fokker 70 positioned for another approach and landed safely on runway 25R about 11 minutes later.

A (qualified) ground observer estimated the speed of the Boeing 737-500 at the instruction "hold position" about 48 seconds after the takeoff clearance at less than 50 knots over ground.
