Certainly automobiles are not made mostly of titanium and the Space
Shuttle
contains more aluminum than titanium. Not sure of the per cent
composition
of airliners, but I doubt it.

Airliners are mostly plastic these days (ie. kevlar and carbon composites) -
with a few bits of aluminium here and there. Metal is sooooo retro!! ;-)
