Zeppelin-Staaken R.VI
The Zeppelin-Staaken R.VI was one of the largest wooden planes produced in the early twentieth century, dating back to the First World War. This aircraft was a four-engine strategic bomber built in Germany, and it was one of the first military aircraft to have a closed cockpit. Only six of the 18 aircraft produced made it through the war, as six were destroyed in crashes, four others were shot down, and two others had technical issues.
Kawanishi H8K
The Imperial Japanese Navy primarily used the flying boat Kawanishi H8K for maritime patrol. This aircraft was designed to fly long distances and was frequently flown alone over the ocean with no backup. The Americans nicknamed this patrolling plane “Emily” during the war, so whenever “Emily” was mentioned over the radio, it was always referring to the H8K. Since it was only used in combat in 1942, it was only fully operational towards the end of WWII.
