cjsnell writes "An amateur high altitude balloon was launched in San Jose, CA on Sunday by some ham radio enthusiasts. Their balloon achieved a rare "float": instead of bursting, it maintained an altitude of ~105Kft and headed east over the continental US. Amazingly, it crossed over Atlantic City, NJ at 2200 local time. The amateur ballooning community was going nuts because this may have been the first-ever transcontinental amateur balloon flight. The balloon continued out over the ocean until it disappeared ~500 miles off Nantucket....and then suddenly, at 1100 MST this morning, radio repeaters in the Azores islands off of Africa started hearing the balloon! Incredibly, it was still aloft and trucking towards Europe/Africa at ~150mph! If it makes it, this will be a new record for the first-ever transatlantic amateur flight. What's more amazing is that teams from engineering schools have been launching balloons from the east coast for years, trying to achieve an Atlantic transit. Out of nowhere, two guys who clean swimming pools for a living launch a balloon from Northern California and break every major record in amateur ballooning in a day. They launched three other balloons on Sunday, one of which set a new altitude record of 136,000 ft. Unbelievable.
