  1. During testing in 1970 a 747-100 was pushed to .99 mach in level flight more than once. In the 1960's during some crazy testing of a Douglas a DC-8 the plane was pushed flat-out in level flight just to see what she'd do. The test crew was able to thrash the DC-8 to a max record speed of Mach 1.012 without any sustained damage, imagine doing that today with safety nanny's shoved up your hind side.

  2. Disappointing that they failed to mention the engine problems that plagued the prototype aircraft. They filled the prototype with batteries to provide emergency power. They took the head of P&W for a flight to demonstrate the problem – the pilots handled the engines normally and flamed out 2 of the 4 engines. P&W up to that point thought the pilots weren't handling the engines correctly – they soon changed their tune.

  3. The initial mock up was built in New York and was a double-deck design, as the initial design concept was effectively two 707 fuselages on top of each other. When the airline chief came to view the mock up they had to enter view the wobbliest ladder in New York city. Jaun Trippe was going to market the 747 on the basis it was a double decker. However, by the time the double deck mock up was ready, Boeing had already moved to the wide body we know today. Source: the book Wide Body.

    So why has this documentary skipped over this aspect of the project?

  4. The 247 was effectively the prototype of the DC-1. Douglas was given the windtunnel data almost before Boeing got it as the models were tested in California.

    The 247 had a design flaw in the cabin – the wing spar passed through the cabin.
