question:  How long did Billy-boy and Grannie Annie travel after heat ray attack?
context: [Transcriber's Note: This etext was produced from Planet Stories Fall 1944. The Spacemen's was a sanctuary, a rest club where in-coming pilots and crewmen could relax before leaving for another voyage. The rule that no females could pass its portals was strictly enforced. There she stood before a frantically gesticulating desk clerk, leaning on her faded green umbrella. But to me she was still Grannie Annie, as old-fashioned as last year's hat, as modern as an atomic motor. Her annual income totaled into six figures, and her publishers sat back and massaged their digits, watching their earnings mount. If Annabella C. Flowers wrote a novel, and the locale was the desert of Mars, she packed her carpet bag and hopped a liner for Craterville. If she cooked up a feud between two expeditions on Callisto, she went to Callisto. Grannie spilled a few shreds of Martian tobacco onto a paper and deftly rolled herself a cigarette. Grannie Annie hailed a hydrocar. But the place was packed with miners, freight-crew-men—all the tide and wash of humanity that made Swamp City the frontier post it is. On the right were nine visi sets, each with its new improved pantascope panel and switchboard. Before each set stood an Earthman operator. When it had subsided, the man continued: "As most of you are familiar with our program, it will be unnecessary to give any advance explanation. I will only say that on this stage are nine visi sets, each tuned to one of the nine planets. At transmitting sets all over these planets listeners will appear and voice questions. For every question missed, the sender will receive a check for one thousand planetoles . Doctor Universe nodded and turned to Grannie Annie who had raised her hand. Questions from Mars, from Earth, from Saturn flowed in the visi sets. Isolated miners on Jupiter, dancers in swank Plutonian cafes strove to stump the experts.
