Not sure if this has been posted before, but this is probably the best (in terms of detail) video showing the F-35 that I have watched:

That was great Martyn.
 
Imagine that, press one button and you hover. Couldn't be any easier, even Mutley could fly it.

The Harrier was easy too. As the aircraft decelerated you just altered the nozzle position to counter the loss of lift. No computers required.

Transitioning from hover to forward flight was also as straight-forward.

The Harrier system was also very simple. They made a seriously flawed design choice with the F-35. There is no reason the F-35 couldn't have had reheat and the Harrier nozzle system. It would have been much simpler and lighter, and none of the design compromises that came out of the poor choice of lift system would have been necessary.

There are all kinds of problems with the F-35. The canopy for example has the frame going up and over the front. So much for all the advances made in single-piece, unobstructed bubble canopy that was used in the F-16! Now you have an unnecessary obstruction in the field of view.

Did you see in the video how it was necessary to dump fuel in order to land???????????????? What the hell!!!!!

Best regards,
Vulcan.

The same is true of many other aircraft.

The operational profile of these aircraft doesn't mean you do short STOL hops when full of fuel. You're going to take off/land STOL but in the meantime, you'll be flying around, burning off the fuel anyway.

A guy flying a sim with full fuel is just demoing it, it doesn't mean they'll be routinely dumping fuel every time they fly.

No it wasn't. Pressing one button, and allowing sophisticated computers to make adjustments faster than a human can, more accurately than a human can, is obviously far easier.
 
The harrier was notoriously difficult to fly, it killed many. Hovering in the Harrier was said to be like balancing on a knife edge of thrust, it required great skill.

Huh, the F35 system may be more complex, but that's for a reason. The F35 is far heavier, requires more power to hover. And in regard to a "Harrier nozzle system", the competitor to the F35 in the trials, the Boeing attempt, did have the harrier nozzle system. It was a complete failure, it couldn't carry the weight, they had to strip off body panels to get it to hover. It also suffered from frequent pop stalls when hovering... just like the Harrier.
 
The Harrier style direct exhaust gas system just didn't cut it and couldn't fulfil the military requirements.
 
The system chosen for the F35 was the best option...  precisely why it beat the Boeing X32, [that utilised the harrier nozzle system] and won the trials.

On 26 October 2001, the Department of Defense announced that the Lockheed Martin X-35 won the JSF competition. One of the main reasons for this choice appears to have been the method of achieving STOVL flight, with the Department of Defense judging that the higher performance lift fan system was worth the extra risk. When near to the ground, the Boeing X-32 suffers from the problem of hot air from the exhaust circulating back to the main engine, which causes the thrust to weaken and the engine to overheat.[citation needed] The X-35 would be developed into the production F-35 Lightning II.
