Assuming the PCs aren't attempting high-order salvage by chasing a
stricken ship into a GG and subsequently EVAing to the casualty, skim
runs IMTU for what GT calls streamlined vessels (I think CT et al call
it "airframe") with CG varies from what you're proposing to relying on a
mix of aerodynamic and aerostatic lift (often above the 1 bar level),
while streamlined ships without contragrav prefer the conventional
throttles-wide-open-hang-on-to-your-hide-and-damn-the-SDBs approach.

Why yes, one group of PCs have had to deal with utility module failure
and subsequent vodka-martini stall during an "easy" skim run.  Why do
you ask?
