HD, jokes apart, there would be SO MANY things to be suggested to aircraft manufacturers.
The industry wants us to believe that we are on the best possible track, as demonstrated by Airbus with the 380.
Bull!!!!!
They are scared of losing money in case something should happen that the public opinion (ignorance, I might say) would attribute to different designs.
So we'll continue to have airworthy, but not crashworthy, airplanes.
We'll continue to have landing gears and engines attached to fuel tanks.
We'll continue to try to avoid disasters, not to make them survivable.
If you think moving the E&E bay would be a great deal, go to the Burnelli site - with an open mind, I hope....
For those who think we live in the best possible world!
