 Which word doesn't describe Tolliver?
Tolliver began to have his doubts the next day; which was "Tuesday" by the arbitrary calender constructed to match Ganymede's week-long journey around Jupiter. His contract guaranteed a pilot's rating, but someone had neglected to specify the type of craft to be piloted. On the bulletin board, Tolliver's name stood out beside the number of one of the airtight tractors used between the dome city and the spaceport, or for hauling cross-country to one of the mining domes. Sometimes there's no reason but them for sending a ship back with a crew instead of in an economy orbit. "Sure," agreed Tolliver thinking, Ohmigod!
