Teijin Escapes.

Because of the earlier accident, the zippers had been removed, a new deflation system, called the upside-down technique was tried. This was done by having two load rings, held together with 4 webbing belts. By releasing the belt buckles, it should have 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 was, that the tightening rope would roll the envelope over and release the hot-air from the upturned mouth. Teijin contained 4.5 tons of air. On release, it never even started to roll. The 600lb rope simply snapped. Teijin escaped.

  Wait -A slide show will start.  

The enormous envelope, without the burner or 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. Here you'll see a small Dutch balloon, being collapsed successfully, using the "upside down technique.

  That system having failed, yet another, the chimney system was tried. Seen here at Sydney University.
