How we got it back
Soundfragment comes here
Immediatelly when it landed, a woman got it. It landed 20 meters from the river Maas in Rotterdam. She tried to call us (i didnt pick up, i was attending a TEDx Delft talk, she thought it was a bomb, so “She opened it ” (=ripped the whole front off). Then she called the police, which said “Oh yeah we know about that, it’s not a bomb”, then i called her, picked it up after a 15minute drive!
