The East Anglia Air Ambulance (EEAA) is landing in Biggleswade on Sunday for visitors to take a look.
It is one of the many attractions at the EEAA Charity Day being held at the Weatherley Centre.
The fun-packed fundraising event also features hot rods, classic cars and steam engines. Police, and fire engines, will be there too.
There will also be children’s rides and many stalls plus a big raffle.
And there’s plenty of music with rock ‘n’ roll acts including Paul Neon, Pagan and The Spree, soul Motown singer Simon Baker and a disco.
North East Beds MP Alistair Burt will be paying a visit too.
The day runs from noon to 6pm and entry is £5, under 16s free, with food and a bar.
