The RAF has reportedly halted flights in and out of its biggest airbase because the “runway has melted” on a day of extremely hot weather.
RAF Brize Norton in Oxfordshire was forced to divert traffic from the runway on Monday morning after the tarmac began to warp in the heat, a source told Sky News.
Another source said contingency plans were in place to avoid impacting military operations.
The Ministry of Defence did not immediately respond to a request for comment from The Independent.
Brize Norton sits in the area of Britain on red alert for extreme heat on Monday and Tuesday, with temperatures on Monday expected to peak at 35C.
The runway at the base usually operates around the clock and is Britain’s main gateway for defence air transport.
The UK’s highest recorded temperature is expected to be exceeded twice in the next two days and the Met Office has declared the country’s first-ever national heat emergency.
