On 3 November 2020, a Boeing 767-300 departing Madrid had an explosive main gear tyre deflation just after passing V1 and tyre debris ingested by the adjacent engine led to its failure. After completing the take off on one engine and burning off excess fuel, the aircraft landed back four hours later without further event. The Investigation found that the cause of the deflation was a piece of unidentified debris of a size unlikely to be detected by normal visual runway inspection methods. It also found that there was scope for improvement in related airport and ATC emergency response procedures.
