Balloons arrive...yay

Seems like the balloons I ordered online for my rockoon concept have arrived, the balloons are old military *junk* but hey they can still float, not as high as the new ones. I ordered these military balloons, six of them and hopefully they perform the task of not popping when filled with helium and perhaps getting higher than 30k feet. Alright than. But the plan is of course is to buy much better newer balloons from a reliable company like Totex.
