That was an odd landing. May 5th 2016, British Airways Airbus A380-800 arrived into Heathrow from Hong Kong . One of the tyres had developed a square semi deflated state.
Tyre experts determined that the tyre was damaged or received a puncture that perforated the casing and leaked during the flight until low/zero pressure. During descent, when aircraft reached a lower altitude, due to the fact that either the hole in the tire closed up (due to low pressure inside the tire) or because the size of the hole did not allow the tire pressure to increase as fast as the outside air pressure, the higher outside air pressure exerted an external force on the tire that compressed into this this strange square shape.
