Witnesses said they heard the planes from their homes as they were 'so loud' but enjoyed seeing them in the skies.

A spokesperson from the Ministry of Defence said it 'looked like' routine F-15 training.

Over lockdown, both the RAF and USAF have been fully operational with training taking place regularly.

In January this year the RAF 'inadvertently' caused a sonic boom over Norwich as a RAF Hawk aircraft completed a high-speed dive as part of an air test schedule.

Another RAF plane, the Globemaster, was also spotted flying over Norfolk on an exercise in August 2020.
