  == F-35 Joint Strike Fighter ==  Hullo, I was wondering about this edit.  It has a lot of technospeak in it (clutch-and-bevel gearbox, LP turbine expansion, etc.) in it that our readers might find hard to understand.  I have two very important questions for you.  Firstly, what exactly does this technospeak mean?  Secondly, what is your source for this information?  Thanks for your time, and a prompt response would be greatly appreciated.  Cheers,
