Publisher's Synopsis
Tom tries, with mixed success, to get someone to go along with him and try out an airplane that he had recently been working on. After getting off to a good start and proving that his concept worked, the plane's engine died and Tom had to volplane back to earth. Upon checking for a problem, Tom found that his platinum-tipped spark plugs. While he was wondering where he could get some platinum, a Russian, who lived nearby, came and offered him the metal he needed. When asking the man where he had obtained it, the Russian told him that it came from a lost platinum mine in Russia that had been discovered when he and his brother (who was exiled in a Russian mine) were lost in the mountains. Later, the Russian authorities recaptured them and discovered the platinum ore samples they carried, but they were unable to find the lost mine. Tom immediately decided to go to Russia with this man, rescue the man's captive brother, and try to locate the platinum mine. To help their search for the mine Tom built a glider. Did Tom make it to the mine? Did he rescue the man's brother? All these and more are answered in the book Tom Swift and his Air Glider.
