Said another way, the air is so thin on Mars, you might as well be trying to
soar on the moon. It doesn't matter that the gravity is less; without air,
you're going to have a 0:1 glide ratio!

Given the lesser density of air on Mars what would be the glide ratio of
a PW-5 starting at an altitude of say 5000 feet? (lesser gravity, too)
Is it worth book a trip in next few years?
