"This officer has been on intruder operations since March 1942 and has acted as navigator on 45 offensive sorties. He has at all times showed the greatest possible keenness to engage in operations against the enemy and has shown exceptional skill in locating targets under all conditions. The pilots with whom Flying Officer Alcorn has flown have damaged several enemy aircraft over their own bases, bombed and patrolled practically all the heavily defended aerodromes in France, Belgium and Holland and damaged much railway transport. He has consistently shown great presence of mind in helping his pilot to avoid gunfire and to take successful evasive action when engaged by searchlights and has gone out of his way to give advice to navigators less experienced than himself. Flying Officer Alcorn's value in keeping up the present high standard of morale in this squadron cannot be overestimated."
