Celebrity aviator Carol Vorderman will join up to 5,000 cadets from across the UK at RAF College Cranwell to mark the 75th anniversary of the RAF Air Cadets.
Ambassador to the RAF Air Cadets, Honorary Group Captain Vorderman will attend the historic national parade and musical extravaganza and meet cadets aged 13-19 on August 13.
Compered by Peter Dickinson, voice of the X-Factor, young people and volunteers will take to the stage for the musical extravaganza, after a precision parade and drill ceremony in front of College Hall by 350 cadets.
Also attending will be VIP guests including the new Chief of the Air Force Air Chief Marshal Sir Stephen Hillier, himself a former cadet.
As well as the huge parade there will be flypasts from the Red Arrows and the Battle of Britain Memorial Flight and the RAF Falcons are set to drop in.
The historic event is to mark 75 years since the formation of the Air Training Corps and several units of the Combined Cadet Force (RAF), collectively known as the RAF Air Cadets.
The day will close with a finale of fireworks.
In preparation for the parade, cadets will attend a prestigious week-long drill and ceremonial camp the week at Beckingham Training Camp, 10 miles from RAF Cranwell.
