I know, Mac. Surprising that they didn?t all fall out of the air!
Maybe there was little or no airflow separation because the brakes were well
clear of the wing surface when fully deployed.

Mike,
Thanks for
the only thing i could see as a variable, would be the wind traveling Up the
windshield and possible skipping over some of the board.
if the board is too short, you won?t have any results. Too tall may rip it off
the roof.
I can?t wait to hear the results.

it would seem at least sufficient for our application.
Is there a way to check resistance while the board with holes is in the stowed
position?

It's a valid test. But "better" testing would be a few vacuum (they also
read a little bit of pressure) set up at strategic locations around the
test section.
While the holes might have more drag.. I bet the flat board causes a bigger
"high pressure" zone.
