First, the skirt is not bearing the weight of the vehicle, the air
cushion is.
The temporary skirting is really only needed to patch up the skirt of
the
damaged vehicle.  Finally, that drop of superglue (between polished
surfaces)
would continue to support that guy in the hardhat, even if he gained
another
two thousand pounds [Time-Life Science: Giant Molecules].

Given that it did not have brakes before it broke down, it is not that
much
harder to control (not that this is an easy task, just not much harder
than
controlling one).
