Teijin Escapes.

  Because of the earlier accident, the zippers had been removed, and a new system, called the "upside down technique" was to be tested.
     With Teijin, this was done by having two load rings, held together with 4 webbing belts.
When the belt buckles belt were released, it left the basket + crew standing on the ground, while the released envelope climbed into the air, only connected by a rope connected to the crown of the balloon.
    The theory is, that the tightening rope rolls the envelope rolls over, releasing the hot-air from the upturned mouth.
Teijin contained 4.5 tons of air. It never even started to roll over.
The 600lb rope simply snapped.
Teijin escaped. The enormous envelope, without the burner or the gondola, rose rapidly.  It was chased on foot, then by motorbike, then by car, then finally in a hired aircraft. The radiant heat from the Sun kept it airborne and it was last seen 80 miles away at about 30,000 feet.

You also see here a small Dutch balloon, being collapsed successfully, using the "upside down" technique.
  Wait -A slide show should start  
  The Aerostat Society was apparently finished, as no further news of the balloon came in. The society had no balloon, and was in debt.
Two months later, a commercial aircraft pilot spotted what seemed to be a parachute in thick forest near Taralga. A bulldozer was needed and the envelope was recovered. Damage was minor, although ultraviolet light would have weakened the fabric.
The "upside down" technique proving unsuccessful, the "chimney technique" was adopted. So Teijin was modified yet again. An open tube, a chimney, was fitted, to rapidly but safely deflate the balloon. The chimney was tied shut with a loop of rope, linked to a release pin. The pin was released by pulling a line.The effect is shown here, during a test at Sydney University.
