I was just checking...
Intruder is right though (thanks also to Bellerophon). My mistake
What I meant is
the heavier glider is
given a speed to fly and the other one is also
given a speed to fly. So they both have given speeds
the same difference...
Nah, it's about glide ratio at the same speed and about time if they fly at their OPTIMUM speeds for their individual weights (masses).
