Concorde might have taken off too early...not withstanding it paved the way for improved airliner design speeds, advanced flight controls and instrumentation,class of comfort and premium service itenerary of all airliners flying today.Where would Fly By Wire technology of today's airliners and bizjets as well as combat planes be..without the pioneering Concorde?It had its design flaws...and the design of adjacent engines must have been seen as a potential hazard during engine failures and fires or tyre blow ups.Comet and VC10 as well as their russian counterparts had similar flaws in their designs.Had the Boeing Supersonic Airliner taken off with its different engine design who knows if supersonic airliner transport might have taken a different track?
