Ironically, his theory helped spawn the F-15, but then he became an opponent of it...

Consider an aircraft weighing 100,000lbs, in a level 3G turn, with an L/D of 10:1 (in that particular set of flight conditions). To avoid losing speed, the engines need to be producing 30,000lbs of thrust.
|Quoting Ferrypilot (Reply 10):|
An aircraft weighing 100,000lbs would be a pretty big plane to be hauling around with a 70degree bank angle and which is what you would have if pulling a level 3G turn.
|Quoting Rwessel (Reply 11):|
But even so, something like a 737 is physically capable of a 3G turn, even though it's not often flown that way.
|Quoting Ferrypilot (Reply 14):|
However I have seen the max. g limit for it advertised as being 2.5 And in which case it would be quite adventurous to attempt to fly even a 60 degree banked turn requiring only a 2 g pull in the type.
...And I suggest to you that were an average pilot to attempt a 3 g level turn (corresponding to 70degrees bank < ) in the 737 there would be a very high risk of an accident occurring. ...As an accidental over bank of only 10 degrees during any part of that turn would suddenly require a 6 g pull to stop the nose dropping and to maintain height. And which I would have to suspect would most likely cause catastrophic structural failure of the airframe.

A plane that size could physically pull such a maneuver off, therefore it would not be far-fetched to say a plane that size could pull such a maneuver off.
