Adventure of the payload

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!

    Hi Tim,

    Would be glad to help out on the 7th if you need any ground crew assistance. Let me know.

      It would be great if you can be at the Aerospace faculty around 13:00 would be good i think. That way we have plenty of time to set up base.
