Which detail supports the central idea?
The suits were orange Racal suits designed for field use
with airborne biological agents and they were the same
type of suit that had been used at Kitum Cave-in fact
some of them had come back from Africa in Gene
Johnson's trunks. The suit has a clear, soft plastic bubble
for a helmet. The suit is pressured. Air pressure is
supplied by an electric motor that sucks air from the
outside and passes it through virus filters and then injects
it into the suit. This keeps the suit under positive
pressure, so that any airborne virus particles will have a
hard time flowing into it.
