Who says it's not possible?
It's thinking like that that gets us nowhere and would have had the A380 being merely a dream...someone out there will get it and when they do I'm going to tell you about it....so keep your negativity to yourself...I believe we can fix problems and I never said it would be easy, so stop listening to your inner gremlins...helps if you keep off the tablets
The negativity and lack of imagination on pprune sometimes amazes me...there are people who dedicate their lives to such an "impossibility" and I think that saying that it's impossible is weak, really...how disappointing to see that on an aviation-related forum...that something can't be done!
