Once jet engine testing stopped, the bunkers at the test cells were used "to store hazardous and explosive material".

The pipes transported the fast moving air to/from the test cells.

The test cell, unique in the world, takes up most of the steel clad structure with its mass of pipes, blast doors and electronics.

With a diesel engine installed in the test cell, Ciatti and his team were ready to explore the possibilities.

The Financial Times of London yesterday published a diagram said to show the test cell used in the experiment.

A test cell was constructed so as to be flooded separately from the main impoundment.

Two other airframes served as a static test cells.

He managed to gather a small number of parts from test cells that would provide an early start.

The two said that an electric current passing through the test cell produced excess heat.

Aviation Repair Technologies holds an exclusive lease on the test cell through 2019.
