Having now viewed the video - his comment about it weighing "five tons" was a bit off as well. I'm sure John can correct me here, but from memory I don't think a Harrier II has a flyable configuration down at 10,000lbs does it? Certainly the original 1127/kestrals had basic weights down there somewhere, but I'm not that sure if even any of the Harrier Is did.
At the other end of the scale I can remember the 34,000lb AUW (or was it 32,000?) clearance trials, but that's a different skillet of trout, of course.
