Algodoo

This is an actual lighter than air craft, I think its thew first in Phun, I searched Phun box and Youtube and found nothing, but the Japanese may have made one already. I know its uglier than Hitler, but it fly`s, there`s also another docking station at the end of the green line floating in mid air, which you just stick the no the thing in the docking mechanism and it will automatically lock in.
I had to make Sim.AirDensity = 0.1 to make a realistically sized craft, in fact, its about the size of a Hindenburg class airship, albeit, 2d and not real.

Controls:
QW-Control movable Ballast
Arrow keys - use directional controller on airship, I originally was using Paragigdm`s Air engines, but I didn`t like the lag and a directional controller is just simpler and you don`t really lose any handling.
G-Let out lifting gas, taps will let out a bit
B-Let out Ballast, you have to hold it for a bit then release it to release a block
D-Door
ENTER(Return)-Hold while moving left with arrow keys to undock
