Worker Inspects Inflated Transition Ring Airform.

Worker Inspects Inflated Transition Ring Airform

After the two halfs of the Ariform are attached to the steel hoop, we slowly inflate the Airform to a low psi. Next, the crew carefully inspects the structure and removes the wooden stanchions. Note the hourglass shape of the stemwall; once the dome is inflated to its ultimate air pressure, the stemwall will straighten up.
