- The mass ratio on an airliner is much less than in a launcher with
- chemical rocket propulsion, for rather fundamental reasons. It is
- therefore not inconceivable that multistage launchers would be
- appropriate even though multistage aircraft are not.

- (Actually, effectively multistage aircraft are in routine use,
- through the use of midair refueling.)
