With the 380 out of the way, there is talk here (Seattle area) of an updated 747 making a comeback should the need arise. Airports are already congigured for it (35+ years ago)
That would not surprise me. The way the market is now isn't the way that it once was, or is going to be in the future. Small-hauler SSTs will be flying in 10, 15, 20 years, and large, long-haul widebody will make a return as well -- it takes a while to be ready for any of it. Thanks llevrok.
