A number of open circuit compressed air breathing appratus sets were also used, the Siebe Gorman Airmaster carried on some pumping appliances.

First, the container may build up minerals from the local water supply which eventually may be become part of the air breathed.

It includes both ballistic missile defense and air breathing threat defense, and encompasses point defense, area defense, and high value airborne asset defense.

However, being an air breathing engine ( unlike a conventional rocket ) there is a penalty for taking on-board air from the atmosphere.
26.
The missiles features a revolutionary air breathing ramjet motor, which will enable them to fly much further and improve agility, the ministry said.
27.
This version of the BrahMos missile will use air breathing scramjet propulsion technology and would be more fuel efficient than a traditional rocket-powered missile.
28.
Consequently, the thrust characteristics of a rocket motor are different from that of an air breathing jet engine, and thrust is independent of velocity.
29.
The increase in technology, such as night vision goggles, air breathing equipment, and metal detectors allows grave robbers to better find and rob ancient gravesites.
30.
The dry season is a likely time for this; there would be little food in the stomach, which would allow its use for air breathing.
