It has been a while since offering a new Aircraft Quiz, so here is a new aeronautical brain twister test.
1. What was the very first year time-frame in an American aircraft that servo tabs were used to successfully cope with heavy pressure loadings imposed on control surfaces such that otherwise the pilot could not overcome them?
2. Name the aircraft builder and 3. The full aircraft nomenclature.
4. What was the top speed of the aircraft that produced the high control surface pressures?
Other aircraft features were retractable landing gear, enclosed bombardier's compartment and an internal bomb bay. (Just to perhaps give you some more clues).
