Optical lift is different from the aerodynamiclift created by an airfoil.
2
This interfered with the aerodynamiclift that normally helps flatten its course and gentle its reentry and landing.
3
When air travels over a wing, it sticks to the surface, and bending flow results in aerodynamiclift.
4
The spaceplanes were limited by the ancient laws of aerodynamiclift and stability, restricting their tactics to classical aerial manoeuvres.
5
Anything without wings, that is, without aerodynamiclift generation, falls in a ballistic trajectory, with the heavier stuff going farther horizontally.
6
From what I understand (which clearly isn't everything) this has a lot to do with aerodynamiclift from the sails.
