The Lincolnshire-based Red Arrows are taking part in an 150-mile flight with their young air cadets today.
It is to mark the 75th anniversary of the RAF Air Cadets and will be the second time in history that cadets have flown with them.
The crew take off from the RAF Scampton in Lincolnshire before landing at RAF Fairford in Gloucestershire in the afternoon.
The cadets, who are all aged 16-19, have been selected for outstanding achievement within the force and will be greeted by TV star Carol Vordeman on landing.
Although the display will not involve aerobatics, the team will be flying at top speeds of up to 400mph in one of the largest air shows in the world.
