 ===== Lift Systems =====
-Static lift can cancel out the mass of a vehicle.  However, these are really only available in two formats:  gas bags and contragravity.  Gas bags were technically obsolete before they were even invented, and contragravity is superscience.
+Static lift can cancel out the mass of a vehicle.  These range from gas bags to lift fans to wings in ground effect to super-science solutions such as contragravity or levitation.  In addition, some air motive systems, such as helicopters, tilt-rotors and ornithopters, provide some lift as well.
-Contragravity will require installed power;  gas bags do not.
