Booster Tube

The Booster Tube is the long pipe running the length of the EDA and into the Attenuator. The Booster Frame is bolted on the Booster Tube. According to evidence found by pchrisbosh1, there are two types of weld present on the tube, a detail which differs from movie to movie. In the first movie, all the hero packs had a thick weld between the top of the tube and the Ion Arm, probably to strengthen the Ion Arm installation on the fiberglass shell. In the second movie, a "weld" of some sort of sealant was added at the base of the tube, where it goes into the Attenuator. The semi-hero props had the booster tube and "weld" molded in, and they actually added the "weld" on the hero packs that they upgraded for the second movie.
