Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

This is a US Navy free balloon as used for initial lighter-than-air training during the 1920s to 1940s. It is fairly representative for a type of aircraft that first flew in 1783 and soon afterwards found a shape and construction that it retained (almost) to this day.

Handling instructions

The ZF Navy free balloon with the envelope shader enabled.

Important controls / keys

Flight controls

  • Gas valve
  • Ballast

Ballast

  • W - Weigh-off to 10% of current weight by dropping ballast. Takes about 10 seconds and only works when on the ground.
  • w - Show current on-ground weight. Only works when on the ground.
  • D/d - Drop ballast in 1%/0.1% decrements.

Gas

  • F/f - Open/close the gas valve.
  • R - Rip the envelope. Use only close to the ground and when you really really want to stay there.
