“Damage to Vickers Wellington Mark X, HE239 ‘NA-Y’, of No. 428 Squadron RCAF based at Dalton, Yorkshire, resulting from a direct hit from anti-aircraft gun fire while approaching to bomb Duisburg, Germany on the night of 8/9 April 1943. Despite the loss of the rear turret and its gunner, as well as other extensive damage, the pilot, Sergeant L F Williamson, continued to bomb the target, following which it was found that the bomb doors could not be closed because of a complete loss of hydraulic power. Williamson nevertheless brought HE239 and the remainder of his crew back for a safe landing at West Malling, Kent, where this photograph was taken.
