The Harrier jet was a success story.
If success is creating a remarkable (and fabulously noisy) aircraft, then yes. But as a practical proposition VTOL and even STOL airframes are complicated, technically challenging, have very high costs in fuel, design weight and capability, and high accident rates. For those rare occasions you need a moderately fast jet to take off from a container ship carrying a tiny weapons load and limited fuel, the Harrier was the answer. For everything else VTOL is always inferior to the runway launched. The vast cost and many problems of the F35B show this. And that's why the USN opted (as should the bunglers of Westminster) for the F35C.
I love the Harrier, I've worked for MoD, I was born on and brought up on RAF stations, but let's be clear that just because you can do something doesn't make it a good idea.
