I’m familiar with low and high bypass ration engines, my question was why are the actual shape of the engines so radically different?
The 737-100 pictured has a very long engine that takes up the whole diameter of the wing, and then some, while the 737-300 pictured below has a much shorter engine casing.
That is what i want to know.

Sounds about right! Don’t get me wrong, the american’s have made some truly great machines, but the classic mentality is always “just make it bigger” Not really suprising the revolutionary VC-10 and HS Trident were not successful overseas. Which is exactly why Concorde was slated by them – Because it was just better than anything they had, fuel consumption and noise aside.

I have read many reports and discussions on the accident to AF 4590. I have as yet never found any answer to my question.
On 22nd August 1985 G-BGJL Boeing 737-236 on take off at Manchester Airport suffered an uncontained engine failure which punctured wing fuel tanks, causing a fuel fed fire which destroyed the aircraft and killed some of the occupants.
On 25th July 2000 F-BTSC Concord ( spelling intentional) on take off at Paris suffered an undercarriage/tyre failure which punctured wing fuel tanks, causing a fuel fed fire which destroyed the aircraft and killed the occupants.
Goodness knows how many millions of £s, $s or Euros were spent putting racing car type kevlar linings in Concorde wing tanks, having grounded the entire fleet almost at once, and ultimately sounded the death knell.
What if anything has ever been done to correct the similar (apparent) tank weakness in the Boeing 737 ?
Your comments and observations appreciated.

Interesting observation – I can’t help thinking that Connie was used as a bit of a scape goat – Many other types have experienced tragic and catastrophic errors (The consecutive DC-10 cargo door disasters spring to mind), but gone back into service without a hitch.
Another thing i’ve always thought, which is probably common knowledge, is that the yanks were constantly trying to urinate on our bonfire, because we had a supersonic airliner, and they didn’t?

You wasn’t perhaps the guy in the silver Vauxhall corsa was you mate?
And i think a thread linking to manston activity would be handy, to deal with the problem of apparent irrelevence in this section of the forum.
