Fareast driver: similar thing happened with the Varsity at Farnborough which trialed FLIR and LLTV. It came back from a trip late at night and OC Flying flew over the airfield to find out what detail he could see and was heard to declare on the tape 'I'm happy to try a landing using that picture'.
So he flew a visual circuit and lowered the gear, only for the nosewheel to block the view of the FLIR, both it and the LLTV sensors being in the forward vision panels in the 'bomb bay' below the aircraft!
