they do, Mojoey, but they only deploy if you drop them from orbit, on a entry orbit, once to a set hight it should deploy, but maybe it's only for earth
I can't find it anymore right now, but just yesterday I saw a screenshot of an Arrow Freighter parachuting a (very) long row of UCGO cargoes...it was on Earth though.
Incorrect. I have parachuted UCGO cargos over Earth by dropping them from the whiteknight. I have screenshots of it too.
For my own Mars drop I was looking at [ame="http://orbithangar.com/searchid.php?ID=4657"]UCGO Cargo Container[/ame] and the Parachute/rocket pack from the World of 2001 addon.
