There is one thing amazes me most about heavy jets-the structure.
And i point to the wing-fuslage joingings. How can such heavy wings join to the fuslage? Is there a possibiltiy of the wings
coming off? How does the wings join to the fuslarge.
And how many G's can a heavy jet like the 747-400 can withstand?
Lastly, the engine pylons-I know there are pins which secure the engines so they can't come off but how can a series of pins
'push' a 390 ton 747-400?
