Most C-90 pilots understand the sequence of events that transpire in the event of a boost pump failure.

The upper portion of the door opened about six inches resulting in an explosive decompression. The pilot stated one of the more unusual aspects of the rapid loss of cabin [...]

A Biostat can keep an outbreak of microbes from continuing to grow, but it won’t kill [...]
