Sorry about that. They should be the last ones you see for awhile, I think.
No, it didn't. For the first round of "Identify This", I tried to use only production aircraft. Two factors have convinced me to include prototypes:
1 - They're really interesting parts of aviation and aircraft design history
2 - You guys are really good, and if I limited the selection to production aircraft, I'd probably have to start using shots of rivets and ELT antennas to make it challenging for you.
Using prototypes here and there introduces a true "hunt" for the photo and even some historical research, as opposed to having to file through some "usual suspects" in a mechanized manner. The key is to keep a healthy balance of production and prototype aircraft.
As you can see by the shots I've used in IDT 4.0 so far, I like to err very heavily on the "production" side of things. The only other prototype I've used in the game thus far was the Lesher. And I still can't believe so many of you got it*
The 728 indeed never flew. I would never normally include an aircraft that has never flown, but I thought the history and development of it made it a worthy, albeit devious, inclusion to the game.
As it turns out, Aeroweanie personally knew the designer. Not surprisingly.
