the cockpit of the x-NUMBER_TOKEN as you might have envisioned was cramped and confusing there were two fly configurations for the plane one with a single joystick and another which had three it also seemingly had as many buttons dials and switches as the engineers could cram in there and a quick side note here the seat for the first x-NUMBER_TOKEN came from an unlikely source the first test pilot scott crossfield had concerns over the seats knowing the speeds this aircraft was expected to attain a normal jet fighter seat simply wouldn't be able to give the support required after some thinking crossfield approached the international harvester company a manufacturer of tractors and farm equipment they had conducted extensive testing and investigation on the response of the human body to a vibrating platform and found the natural frequency of a human spine the rate at which an object vibrates when it's disturbed the outcome of this research was a seat that a person could sit in and withstand intense vibrations without compromising their spine as a result the first x-NUMBER_TOKEN to fly had a seat from a tractor the pilot seat was fitted with an ejection system but this could not be used when the plane was making hypersonic runs if the pilot ran into difficulty they would have to drop down to a more manageable speed before they could bail out okay so back to today's video in just a moment but first a quick word from today's sponsor surf shark d is the internet i'm guessing that you might and unfortunately the internet is all kinds of weird there are people out there who want to ruin your day they want to take your details they want to steal your identity fortunately surf shark has hair clock this search is database for your passwords which sounds bad but no surf shark are the good guys they find it they let you know you can change that password and you're back in the warm comfort of safety and while you're in that warm comfort of safety maybe you're like let's watch some netflix it's christmas i want to watch elf but what's this it's only available in europe and you live in the great white north of canada terrible but surf shark is going to fix that right up higher up the vpn and boom very sneaky now you're in europe through the magic of vpn technology and you can watch all the world feral you can handle surf shark is also totally unlimited so if you want to download talented knights in raw NUMBER_TOKENk go nuts no logs great support NUMBER_TOKEN-day money-back guarantee if you don't like it right now you guys can get NUMBER_TOKEN off in four months for free through the link in the description below or use my code mega and now let's get back to today's video
