Unbelievably bad !
The Bugatti 100 wasn't a JET , much less an "advanced fighter jet". (Note to the author: Jet isn't synonym with combat aircraft).
It wouldn't be computer controlled . No computers with the right size and speed for controlling an aircraft where available (also, for the size, the control surfaces would be "muscle" powered, as where all aircraft of comparable size and era).
Being on the prototype stage, it would not ever be combat ready and in wide operational use for it to make any difference on the Battle of Britain (The prototypes for the Spitfire and the bf109 had first flights in 1936 and 1935 , operational around 1938 and 1937).
Compared to the previous issues, the "zero-drag cooling system" is of little consequence.
Also, no excuse for the author not being an "expert" on the subject .
Some basic fact checking ("oh, look it s got a propeller" or "when was the first flight control computer introduced ?") would keep the piece honest. (but would certainly intrude upon the the sensationalist tone).
