Two things impressed me most, one big, one little. The big one was NullGrav, of course. Back in 1970 I had known about the Babson Institute gravitation research but I had not expected anything to come of it—and nothing had; the basic field theory on which NullGrav is based was developed at the University of Edinburgh.
We'd taken off with a null-grav tug and slipped into second-order matrix within six hours—all very fast and painless, thanks to the Luanae.
She might as well try to penetrate null-grav fused steel.
She hadn’t trained in null-grav, that much was obvious.
