This reminds me of the time I saw some dude get in the jet 3 consecutive spawns in a row and every single time he did the exact same thing. Drove down the runway and slammed into the cliff wall. I gotta tell you, I laughed.
As far as flying instructions go, Chris really gives you enough info. For the US hover jets, you just hold back and you will eventually start floating up and up, once you get high enough, start holding forward while keeping the nose pointed up and youll shoot off. For the non hover jets, they all have ample runway space to take off normally, you just hold forward constantly and you should be able to take off from anywhere after 50% of the runway.
Tight turning is really the hard part of jets.
