4 in a Canberra
98 Sqn Cottesmore, operating E15s in the Calibration role. Airframe nos were WD944 (T4), WH981, WH983 and WJ756 - can't recall the others. Typical sortie to cal an airfield approach radar would involve the crew plus 2 Flight Checkers (1 on the Rumbold seat). Transit to the relevant airfield, land and drop off the Checkers. Cal sortie, then land, turn-round the jet and scoff the cabin-trunk sized packed lunch. Further cal sortie, land, engines running pick up of the Checkers, then RTB Rutland for Ruddles finest. 4 trips and approx 5 hours flying for the day in a Classic Jet. Halcyon days.
