Seen in yesterday's post as well, this is the Westland Lysander III. Introduced into the Royal Air Force in 1938, the plane proved to be too slow for the Messerschmitt 109, but ended up seeing a variety of uses through the war in Allied air, particularly in terms of reconnaissance and insertion and extraction of agents in occupied Europe. The Royal Canadian Air Force made use of these as training craft. This one was restored by RCAF personnel as a centennial project and presented to the museum in 1968. The bicycle beside it is a folding type used by paratroopers.
The Lancaster dominates this section, and this one, a Canadian version of the dependable bomber, is best seen from multiple angles. Here we have the rear gun turret.
Another gun turret stands nearby on its own. The Glenn L. Martin Company made them for the B-26 Marauder bomber, but they often turned up in Lancasters.
This is described in the panels as an anachronism of the war. The Fairey Swordfish was a biplane probably more suited to the First World War, yet served throughout the Second World War with specialties including torpedo bombing and anti-submarine warfare. As slow as this plane could be, the Swordfish was known to have sunk more enemy ships than any other British airplane, and had a hand in the sinking of the Bismarck. The RCAF made use of these planes too.
