Allison grinned but didn't reply. What Fred said was true. Ordinarily a mission was planned several weeks in advance and carried multiple tasks that kept it up for three or four days. But this one had dragged the two-man crew off a weekend leave and stuck them on the end of a flight that was an unscheduled quick look, just fifteen orbits and back to Vandenberg. This was clearly a deep range, global recon-naissance - though Fred and Angus probably knew little more. Except that the newspapers had been pretty grim the last few weeks.
The Beaufort Sea slid out of sight to the north. The sortie craft was in an inverted, nose-down attitude that gave some specialists a sick stomach but that just made Allison feel she was looking at the world pass by overhead. She hoped that when the Air Force got its permanent recon platform, she would be stationed there.
Fred Tomes - or his autopilot, depending on your point of view - slowly pitched the orbiter through 180 degrees to bring it into entry attitude. For an instant the craft was point-ing straight down. Glacial scouring could never be an abstraction to someone who had looked down from this height: the land was clearly scraped and grooved like ground before a dozer blade. Tiny puddles had been left be-hind: hundreds of Canadian lakes, so many that Allison could follow the sun in specular glints that shifted from one to another.
They pitched still further. The southern horizon, blue and misty, fell into and then out of view. The ground wouldn't be visible again until they were much lower, at altitudes some normal aircraft could attain.
