So though I wish Orbital well, their track record for trouble free first
launches is not great. Lets hope this one is an exception!

Even the established players have had failed launches of "new" launch
vehicles, which is why Orbital is performing this test flight.

Incidentally what was that launch vehicle called in the 90s that launched
from the same site but blew up leaving a couple of out of control solids
racing upward? I believe it was cancelled shortly after that failure.

I don't know that answer off the top of my head and am currently too
busy with "real work" to look it up.
