What is the point of the _short_ take off?  If the jet can stand in mid-air and land vertically, shouldn't it be able to take off vertically, too?


F35B specifications show weight empty 32,300#, maximum weight 60,000#, and vertical thrust 40,500#. Takeoff weight is more than vertical thrust, so it needs a short takeoff to overcome the extra weight when full of fuel and armaments. That's my best guess.


The F35 can save a lot of fuel during take-off it if uses a short horizontal run along with vertical assist.

Pure vertical eats max fuel and has a higher likelyhood of tossing debris back into the jet body.

Now, it's time for Tim Benson to come out with his very own latest and greatest.


Naa, the Brits were using their Hawker Siddeley Harrier in the 1970s/early 1980s (Falklands!!).  They think it is "old hat"  :D 

Must've been a good plane, the USMC used them from 1971 onwards
