(Perhaps my craziest true quiz yet?).
Name the production aircraft that was built under multiple different model numbers and in at least 32 variants. Hint-one version was perhaps the very first known aircraft to be tested by a government agency for bird-proofing by firing dead chickens at its windshield-with live monkeys strapped in the cockpit seats and photographed during testing. (I am NOT putting you on!)
1. Manufacturer?
2. Model number/s?
3. Date of first flight?
