Biggest amateur-built sub sinksowner is suspected of killing passenger [Updated] | Ars Technica

Believe it or not, there's a crowdsourced, open source non-profit attempting to build a sea-launched suborbital rocket. Called Copenhagen Suborbitals, it even had access to a submarine. Aclub associated with the venture completed the sub in 2008, designed by Peter Madsen, a Danish inventor who is co-founder of the group. That submarine is now at the bottom of the sea, and Madsen is being held by Danish authorities on suspicion of "unlawful killing"a precursor charge to manslaughter or murder.
