UPDATE: Amazing sight as RAF Puma helicopters fly over Bucks

A spectacular formation of Puma helicopters is set to fly over High Wycombe tomorrow. 

On July 7, a formation of up to 10 of the impressive-looking aircraft will leave RAF Benson for a national flypast at around 10am. 

After RAF Benson, it will head over RAF Halton and then RAF High Wycombe, before heading to RAF Northolt at roughly 10.35am. 

It will then make its way up to RAF Scampton for around 11.55am. 

After that, there will be two more legs of their journey taking in different areas around the country throughout the day. 

The special national flypast will mark 50 years of the Puma. 

The first Puma helicopters were delivered into service in 1971.

RAF Benson said: "A formation of up to 10 Puma helicopters will depart RAF Benson tomorrow morning as part of a training sortie that will include flypasts of notable locations for the Puma Force over the past 50 years.

"This includes sites that hold historical significance for the Puma Force as well as those that provide support to delivering current Puma operational capability.

"Unfortunately we are unable to fly over everywhere. The maps provide an illustrative example of some of the locations that will be visited and the approximate timings. They remain subject to change at short notice."

Anyone who sees the formation is asked to share their images using #Puma50 on social media to help the RAF commemorate five decades of service.
