Let it not be missed that the Sea Harrier ski-jump take off was designed by a sergeant on the back of a fag packet.

In the US, 74% of adults are overweight, the average male weighs 196 pounds, the average female 168. The world average for adults is 137.

Yes, we are fairly fat.

"Yes, we are fairly fat".

Terribly non-PC, coming eastwards from the country which started the craze!

Aren't you supposed to say "gravitationally-challenged" so as not to offend those of a higher wake turbulence category?

'Twill soon be a hate crime over in EU to use such an abusive term in public or written communication, punishable by attending diversity training etc.

Years ago flying offshore from Aberdeen.

The so-called standard weight for the offshore passengers was 180 lbs.; 170lbs for him plus 10lbs. for his wet suit etc.. This oil company had a policy where they were weighed individually because that, in most cases as they weighed less, they could get more freight on.

I planned the trip and sent down the payload to traffic. They phoned up shortly after and asked if I could take some more to which I refused. Later on along came the manifest and I noticed that the passenger weight was an exact multiplication of 180lbs.

I went down to query this remarkable coincidence.

"They were too heavy when we weighed them so we reverted to standard weights."

Standard weights and consequential problems. I remember an incident years ago, on a small turbo-prop, I think. It was carrying a group of pax who had been to a coin collectors fare. They were stout gentlemen and had light overnight bags in the hold plus carry-on. The a/c performance was sluggish. Later it turned out that the carry-on contained their coin collection and was way over the 5kgs or whatever the standard allowance was. Each pax was a few kgs over the standard; multiply the whole lot by 30 pax and the overweight could be felt in the trim and overall performance.
I think they got away with it, or was there a crash? Some will remember better.

If you can be slightly more specific than "that accident in CLT", it should be relatively easy to establish whether the probable cause involved a loading discrepancy.

I forget the type but it was a small turboprop and the captain was female...the shifting weight due to gear retraction caused that airplane crashed into a hangar

That was certainly at Charlotte, and did involve the aircraft hitting a hangar, but the probable cause was established as incorrect elevator rigging and a CofG substantially aft of the limit, causing an uncontrollable pitch-up.

So nothing to do with the landing gear (the MLG retracts forwards on the 1900, so retraction couldn't have contributed to the pitch-up).
