Thomson emergency/overweight landing BHXFlight TOM 7260 from East Midlands to Tenerife on 22 November 2016 turned back towards East Midlands and circled south of the airport for a while before diverting to Birmingham.
I do not know the reason for the above, but the 737 was reported overweight for the landing – despite having burnt off some fuel while circling – and requested fire service attendance.
Landing overweight means landing faster and heavier than normal, so the ‘fumes’ around the wheel after touchdown may have been due to overheating brakes rather than a symptom of whatever caused the diversion.
