I like the "Service Ceiling (Estimated)" part given that the Ayr refused to get airborne on its first trial and the project was abandoned. The stub wings were supposed to carry bombs which would be underwater when the aircraft was afloat. What could POSSIBLY go wrong with that concept?
The Ayr has to be on the list of "World's Worst Aircraft" IMHO!
