MAY help minimize drag
To help resist drag, can add something with
a sharp edge at the front (ex. two cards
forming a triangle)

Delating balloon
Helped hovercraft glide
and create upthrust
Plays the same role as the fans
Make hole on hull (for the balloon to fit)
bigger than the hole underneath the hull
(genenrating lift)
A greater SURFACE AREA of the terrain will experience the "wind", so a greater SURFACE AREA of the hovercraft hull will experience the "wind" and help generate lift
The force will be more equally distributed, which
will help the hovercraft "float", so generate lift
