Stuck on the very first number. How many sq. feet you figure
there, to build and market 100 planes/year? By golly, at our
airport there's decently sized and appointed hangar bldg for you, a
former bizjet maintenance facility. The annual ground lease the
bldg.owner (would be you if you had built - for $1 mil,) pays to
the airport is $50,000! So, I guess Acme Airplane Co. leases a
bldg. elsewhere. That means you still lease space at the airport
for testbed and demo planes. Since this is a commercial operation,
the airport might charge much extra, not just T-hangar rates.
Figure $20K there. You'll have travel and dead time costs for the
employees shuttling back/forth, and some duplication in staffing to
work on and sell the planes. Like your one busy sales guy has to
go 30 miles to meet a prospect who shows up an hour late.

Remember if 100 units turns out to be a pipe dream, your overhead
don't shrink much. Was that a 5-year bldg lease you signed?
