First U.S. satellite launch failsIn 1957, America's first attempt at putting a satellite into orbit failed when the Vanguard rocket carrying it blew up on the launch pad at Cape Canaveral, Florida. With a series of rumbles audible for miles around, the vehicle, having risen about four feet into the air, suddenly sank. Falling against the firing structure, fuel tanks rupturing as it did so, the rocket toppled to the ground on the northeast or ocean side of the structure in a roaring, rolling, ball-shaped volcano of flame. |
