I think Barnaby slipped a decimal point there. I can't do the math
on the Europa vertical fin/rudder, but I researched and found entire
tails (all 3 surfaces) on light aircraft come in with a D/q of about
.3 sq.ft. Cylinders are very draggy, but a beacon lens of say .04 sq.
ft. frontal area requires a huge drag coefficient to exceed even .1 in
drag area.
Any aerodynamicists out there to verify this? Or at least someone who
stayed at a Holiday Inn Express last night?
