Until yesterday, I couldn’t tell a pico balloon from pico de gallo. It turns out, these things circumnavigate the globe on 40 ma and solar power and weigh about a half ounce. They’re out up there by a bunch of STEM kids.
A half ounce? Really? I’m gonna guess that’s not enough to snuff an engine and I wonder if it would even nick a windshield. A starling–which won’t snuff an engine or nick a windshield–weighs for time more.
I say let them fly the things.
