On 3 December 2020 an Embraer 195-200 on final approach to Sao Paulo Congonhas was given clearance to land on a runway which the same controller had already cleared a Boeing 737-800 to line up and wait on. Despite good day visibility and a late call from the E195 crew querying an aircraft on the runway, only a call from the 737 prompted the controller to instruct the E195 to go around which they then only commenced after a repeat instruction. The resulting vertical clearance between the E195 and the 737 was calculated as having been only 22 metres.
