Here we see a Handley Page Hampden of No.144 Squadron being prepared for a raid. Note the crew members entering the aircraft via the rear gun position, using a ladder to climb up the corner of the wing. The squadron is confirmed by the partly visible squadron code, which has to be 'PL', the code for No.144.
Many thanks to Roger Griffith, the nephew of Sgt. A.J. Griffiths of No.144 Squadron, for sending us these pictures.
