Sky News reported that flights have been put on hold at a military base in the UK due to the hot weather.

A source told Sky News that the flight line at Royal Air Force Cranwell became softer. The source said that all flights had to stop on Monday and Tuesday.

Sky News was told by a source that flying training for pilots was also affected, but that the training will continue in an alternative area.

The UK's Met Office issued an extreme heat warning on Monday due to the high temperatures.

The source told Sky News that tar stuck to the boots and wheels of the two aircraft.

Sky News reported that an investigation had been launched into why the flight line was experiencing problems, despite the high temperatures being a factor.

In an interview with Sky News, a source said that all flights at Cranwell have been stopped because of the heat.

Around 60 students have been affected by the disruption this week. The source said that the trainees were frustrated.

Insider requested comment from the RAF outside of normal working hours.

The main aircraft service area at the base is not available for routine use.

The facility's website states that Prince Charles began his flying training there.

There are other airlines that stop flights when theRAF does. Airport workers and flight crew are in short supply. Airlines were told to stop selling tickets and caps on passenger numbers by the airport.
