Inside another building is a "Battle of Britain" display. This is a Short Sunderland flying boat. It was heavily involved in Allied efforts to counter the threat posed by German U-boats in the Battle of the Atlantic. On 17 July 1940, an RAAF Sunderland performed the type's first unassisted U-boat kill. Sunderlands also played a major role in the Mediterranean theatre, performing maritime reconnaissance flights and logistical support missions. During the evacuation of Crete, shortly after the German invasion of the island, several aircraft were used to transport troops.
