Hint: Look at the date and what happened to three large British ships of the same general type on that day and how history repeats itself.
HMS Hood. Battle of Jutland was fought on that day in which three British BC blew up: HMS Indefatigable, HMS Queen Mary and HMS Invincible, on which admiral Hood lost his life. HMS Hood was officially designated as a BC.
"A three-quarter mile stretch was market out, and timekeepers stationed, while the driver was instructed to keep his foot down. ....... so fast that the timekeepers forgot their task, and the driver, unable to turn or brake in time, vanished in to the trees." What were they testing, and for bonus points, where and when?
They didn't test the tank but something else, something that was latter used in many other tanks, and it happened at the start of 1941.
Just an off-the-cuff guess: Some fool slapped a massive supercharger on the engine boosting its horsepower substancially.
I hope they had air-bags in that thing. Didn't the Crusader have limited head room the way it was? Something about the turret smacking the driver in the head during a traverse? Into the trees huh? Ouch !
They were testing the Meteor engine, which was basically RR Merlin engine without supercharger, in a modified Crusader tank and the results stunned everybody present. They estimated that the tank achieved more then 50 mph. New question: Which class of capital ships came out of requirement called "Rhadamantus"?
Rhadamantus.......Butterfly (Mariposa) ? Tube/funnel web spider ? Pugliese cylinders for torpedo protection ? Wing(like) bulging sides ? Battleship? Came out of requirement ? .... From requirement, or after requirement ?
The requirement, that lead to construction of that class was called Rhadamantus. The class was build during WWI and fought trough WWII. Well, half of it.
