(Googling Sea Launch) Owned by Boeing & others, 8 successful launches
since 1999?

I think I remember posts saying that by being in the middle of an ocean,
they avoided some (but not all) of the government paperwork.

I guess it helps if the launch site is on an east coast or in the middle
of an ocean. Although it seems Guiana & KSC would enjoy railroad & other
infarastructure Sea Launch has no access to.
