I was wondering if the airlines nowadays aren't building their fleets too much on 'vapor-ware'?!
I see them buying like nuts planes that haven't even lifted on wheel in the air yet. They seem to believe anything A or B promise.
How can they have so much confidence? How was this dealt with before, in the 70's, 80's, 90's. I thought at that time they (most of them) first waited to see how a plane really flies before ordering 50 pcs.
Am I the only one who thinks that way?

For transport-category jets I think it's always been the case that an aircraft manufacturer will wait to get a "launch customer" before committing to build a certain type of airplane. Part of that is the manufacturer working with the airline to design a plane around the airline's needs, and part is just some risk-sharing on the part of the manufacturer.
In the past this strategy has come back to bite manufacturers whose airplanes haven't met their promised design specifications - see Convair 990 (too slow), L-1011 (too late), MD-11 (too short range). But these days with advanced computer-based design, modeling, and simulation, manufacturers can be quite accurate in knowing how their designs will perform before they're built.
