Worldbuilding fun

[Sirrocco]

Mostly I'd just been saying that the crash (whatever it was) would have to be significant enough to either set back development (at least in stellar exploration) by *hundreds of years* (or more), or somehow obliterate all record of that star system as a destination. (alternately, it would require that the folks back home Just Not Care, which probably means that the society started with a group that self-selected for some odd religious/politicalsocial views and wated to get away to build their own little utopia.) This is not actually neccessary information for the story - all the peeps here know is that Bad Things Happened and then No One Came. Ignore the question - it's outside of scope. (Unless you want to use it as an excuse to pick some religious/philosophical/governmental/whatever whackos as initial settlers.)
