The correct answer is the Boeing 314. It outstripped all rivals in size, with twice the size of the Sikorsky S-42 and outweighed the Martin M-130 China Clipper by 15 tons.3 The 14-cylinder double-row Wright Cyclones were the first to use 100-octane fuel. The Boeing 314, the finest flying boat to go into regular commercial service, weighed 40 tons, and the first batch cost $550,000 per aircraft.
The correct answer was submitted by jeaton, intruder38 and Blackwolf3945, so the tie continues! Tie Breaker #2 will post in a few minutes. In the event that the tie is unbroken after 3 questions, all will be declared co-champions and Series #13 will commence. Congratulations to our winners and thanks to all who participate (and send me great extra info!)
