Marham 69. As far as I can remember (We are going back a bit now) the canopy did not go because the cabin had not depressurized when the jettison handle was pulled. The depressurizing was initiated by the Abandon Aircraft switch on the Captains left window panel which would, when the cabin differential became zero, allow the canopy to be lifted off by the aerodynamic effect over it. I remember Bill Palmer only too well having had the quarter next to his.
