I folded out the membrane keypad from the seatback entertainment unit and started checking out the system's data retrieval function. Not bad for a mobile unit. Somewhere deep in the plane's electronic guts an optical chip contained the latest editions of the Columbia HyperMedia Encyclopedia, plus the World Almanac and Book of Facts, plus some fairly funky search algorithms. All for the convenience of Global Airways' cherished passengers (and to keep them occupied so they wouldn't drink too much and hit on the stewardesses). As the suborbital hurtled on, five times as fast as a rifle bullet, I started working out some search strings.
