M. LehmanI understand what you're saying. The comparison I would make is to point to modern airlines- the big ol' 747 is being supplemented and phased out in favor of smaller, more efficient jets that do the same job for far less overhead to the company. And of course the planes flown by regional airlines are smaller still. I think that a similar model could be applied to the luxury transports the fly the Orcas, Beluga, and Dolphins.
Fair enough. Hadn't thought of it in those terms.
