Bob, I'm going to guess that the heavier aircraft will glide further.
PE=mgh, so it has more stored energy to be converted to kinetic energy

as it

glides.

Yes, but KE = 1/2 mV^2, so the mass is in both terms and just drops out.

David

Yes and that is why it is important to have your Fowler flaps down when you crash :-)
