HAB fans stalk gorgeous globes
Armchair HAB aficionados were able to follow the two globes' progress online, although Anthony suffered intermittent transmission problems which led him to conclude late on Saturday night that his payload had been lost.
PIE and AVA invade Europe
On Sunday morning, though, AVA was back on the air over the Czech Republic, just before balloon burst and a landing on an Austrian mountain, right here.
Cue an audacious rescue mission by Brano Janicek, Juraj Marsalik, Radim Mutina and Peter Vittek - a group of Slovakian HAB enthusiasts from stsproject.net, who assembled their kit...

Dave's Pi payload, meanwhile, decided not to follow its projected course towards Poland, and hung a right to transverse Switzerland, before probably coming down in France on Sunday morning.
