It was the Lensman series, but the trick was to neutralize inertia, not negate it. The Boskonians apparently once attempted to negate inertia by overdriving a Bergenholm, but even Kinnison couldn't understand why :-)

Is he the guy mentioned in the film "Flight of the > Phoenix"? I haven't seen "Flight of the Phoenix". John Stringfellow. His flying machines were exhibited at the Crystal Palace. He almost had it -- his patent included adjustable horizontal surface in the tail and a vertical rudder. He realized a lightweight engine was essential, and his demonstrated model had one that was good enough to fly (without a pilot) for a short distance. -- Patrick

Plenty of people laughed at Darwin, just as they laughed at poor Lord Monboddo before him. Take a look at C.D Darlington's "Genetics and Man'. Paul Magnussen

Not exactly the same. Some people did have a natural immunity to the bubonic plague. They were often the ones who lived. It has recently been discoved that this natural immunity (a genetic mutation in the cell structure) also imparts immunity to HIV (which attacks cells via a similar mechanism to bubonic plague). > > Geoff. > > -- > Geoffrey S.
