An Easyjet plane sparked panic in Liverpool as it circled above the city for "more than two hours" - at the same time as an RAF fighter jet.
A host of people took to Twitter after seeing both planes doing the same thing.
A member of public, Karl Voice, also contacted the Wirral Globe after he saw the Easyjet plane performing "evasive manoeuvres" with its landing gear down over New Ferry.
He told the paper the plane had been circling over Liverpool's John Lennon Airport from 11.30am. And an RAF fighter jet had been spotted following a similar path.
But rather than being anything sinister, it transpired that both jets were taking part in a "perfectly normal" routine training exercise.
Speaking to the Liverpool Echo, a spokesperson for John Lennon Airport said that in crew training "pilots have to take off and land multiple times" and it was "pure coincidence" that the RAF Hawk, which came to Merseyside from Anglesey, was there at the same time.
The spokesman added: "We've had a number of calls today but it's one of those things that happens from time-to-time. The plane will be here for the next few days doing the same thing – it's part of a training exercise."
