Some photos of the upgraded Chinook HC4 flown by 27 Squadron based at RAF Odiham in Hampshire.
It's a muscular looking tandem rotor helicopter that provides heavy-lift support and transport.
This newly upgraded version is shown for the first time on this years air show circuit, with the crew demonstrating it's impressive performance.
A wave to the crowd.
A shot showing the rear ramp door open.
And an even bigger wave!
