I couldn't help but notice that the JSB version of the 747 has a lift-ratio
which would make a sailplane pilot envious. One can glide about with full
flaps, gear out etc with AoA at 30--40° in 80 kias and keep it level. ;)

When running it with --debug-level=debug I get some numbers on JSB's idea
about drag, for instance:

 Drag_at_zero_lift
 VECTOR
 Rows: 5 indexed by: mach-norm
 0.0000  0.0220
 0.2000  0.0200
 0.6500  0.0220
 0.9000  0.0240
 0.9700  0.0500

and:
 Drag_due_to_alpha
 VECTOR
 Rows: 3 indexed by: mach-norm
 0.2000  1.1300
 0.6500  0.2000
 0.9000  0.5000


I don't know exactly how to interpretate these numbers -- are they way out
of line?

If they aren't, then somehow drag forces are ignored. *No* plane flies like
that. ;)

Reverser is also no functional. Can't tell if this is simply not
implemented or if this has something to do with drag (potentially) beging
dropped in the FDM.

The testbed being used here is a fresh cvs version.
