From the above link:
9 Apr 1967: First flight of 737-100.
8 August 1967: First flight of 737-200, the 5th 737 to fly.
15 Dec 1967: FAA Type certification of 737-100 and -200.
I suppose there is the commonality of the fuselage/nose with the 707/727 but it stills seems miraculous that certification just took 8 months for:
- 2 different airliner versions;
- with a novel engine installation; and
- IIRC, the latest, state of the art flight control system (later implemented on on the 747).
How was this acheived? Was it just a case of everything going right all the time?
