Sergeant Cheryl Done, 41, is a physical training instructor at the camp but five years ago was an exercise remedial instructor at the Headley Court Defence Medical Rehabilitation Centre in Surrey. Jon, who won three silver medals at the Velodrome during the Paralympics, was seriously injured in Iraq in 2007 and was treated at the Surrey rehab centre by Sgt Done. Sgt Done, who represented Britain as part of the bobsleigh team at the 2002 Winter Olympics in Salt Lake City, found herself back at the Olympics heading up one of the pedestrian screening teams at the Olympic Park. The teams role was to ensure everyone was checked through airport-style security, ensure all bags went through the x-ray machines and confiscate any prohibited items. She said: It has been fantastic to see Jons achievements in cycling and how far he has come since his injury in Basra. The Paralympians have all been so inspiring. In total, 20 personnel from RAF Wyton and Brampton went to London 2012 to support the Venue Security Force across a range of Olympic venues, including the Olympic Park and Wembley Arena. Policemen, medics, imagery analysts, engineers and administrators were involved in security patrols as well as vehicle and pedestrian screening. Civil servants also made a significant contribution, many taking annual leave or fitting in shifts round their work commitments to act as Games Makers. Sergeant Jacqui Bowyer, 39, is a member of the Defence Equipment and Support organisation at RAF Wyton. She was working in the Falklands when her name was put forward by her bosses and had only been back in the UK a few weeks before the Olympics started. Working in the pedestrian screening area, Jacqui led a team of 12 RAF personnel. She said: It was extremely hard work but looking back I am pleased I was part of it. When David Cameron and Sebastian Coe came through my area on their way to a press conference the Prime Minister made a point of coming over to shake all our hands and thank us for the work we were doing.PROUD PERSONNEL: Left to right are Senior Aircraftsman Chris Peck, Sergeant Jacqui Bowyer, Sergeant Si Rees, Natalie Bignell (Games Maker), Senior Aircraftsman Afyah Bubb and Senior Aircraftsman Ash Allan, who helped out during London 2012.REUNITED: Sergeant Cheryl Done and fomer RAF serviceman Jon-Allan Butterworth.
