  1. Solid stages might be cheaper.

    The rocket (originally the Cygnus) was originally designed to make use of spare Minuteman ICBM parts, which are solid fuel rockets all the way.

    Thus the solid fuel design (and the launch site). Also makes for very rapid erection and launch, as there's no fueling needed.

    Of course you're transporting those big and heavy roman candles from the factory to your facility to your launch pad which I'm sure will make some people a bit anxious, and you can't shut down the engine and let the whole thing drift down to a more or less controlled crash in case of mishaps.

  2. either that or bits hit other bits they shouldn't when dropping a stage (usually boosters or struts hitting the next (central) stage rather than breaking away cleanly).

    Had a rather spectacular case of that yesterday where everything except the orbital stage broke away cleanly (despite proper staging) and THEN exploded a few seconds later, leaving me with Bob in his Mun lander floating around in mid air about 10km up :)
