Blue and red dye stains on the 'line' at RAF Scampton, Lincolnshire, home base of the elite 'Red Arrows', Britain's prestigious Royal Air Force aerobatic team. The spilled dye provides the team with their distinctive red, white and blue smoke (a vegetable dye and diesel fuel mixture) during their air show display routines. While on the ground, this non-toxic derv/vegetable dye is injected into a vacuum under pressure into the jets' modified belly-pod which in varying amounts of concentrate, gives off a smoke via three nozzles that point down into the jet's efflux, the exhaust that exits the jet pipe at 500°C. For a display, the pods hold enough dye for 5 minutes of white smoke, 1 of blue and 1 of red while the Synchro pair uses slightly more. 7,200 gallons of dye during the entire 2004 season and since 1965 they have flown over 4,000 such shows in 52 countries.
