The problem is not the amount of drag. It's sudden changes in drag coefficient and direction that I'm worried about.

I don't necessarily disagree with you but there has been cases where civil lawsuit has been won after a criminal was lost... The OJ Simpson case comes to mind!

I always go to El Camino next door, especially when I have pilot friends in town... Great open air Mexican restaurant, and the planes go right over your hear.

Kind of a weak lineup this year, don't you think? Especially missing P1, 918 and the Los Lobos "Lalalalala Ferrari"!!!

This parking structure is called the Mountain and is located in Copenhagen. On the back it has residential condos in steps so everyone has their own patio/rooftop garden.

This one has been a favorite of mine since I was a kid...

I don't think the amount of drag is the problem... It's the sudden change in drag and direction of drag that could dangerously affect the attitude of the aircraft.

If the plane was flying at 120 knots then I don't think it would be a problem either, but I doubt it would be possible to stay upright on the board at that speed... But at the low speed that I believe would be required to make it physically possible to ride the board the plane is extremely sensitive. I would compare…

If the drag coefficient was flat like with banner towing then I don't think it would be a problem, but the constant change in drag from change in direction of the wingboard combined with with a required low speed of the aircraft could affect the stability of the aircraft.

Not advocating for war... Just the limited use of the word "warmongering"!

With tow planes and wing walkers the forces on the aircraft are static. Once the banner is out, power can be adjusted and the pilot can easily maintain a stable equilibrium in flight.

I don't think that yawing would affect a stall much, unless airspeed is decreased more than the -20 knots mentioned above (which could happen if the yaw initiated a forward slip without the pilot increasing throttle or pitching down)... A spin is a form of stall which means that the airflow over the wing is…

Is there any airspace not governed by the FAA in the US?

The short answer is Yes! Stall speed on a C-172 is 36 knots in landing configuration (full flaps) and 44 knots in clean configuration (no flaps)... You would use a clean configuration in this instance as the flaps would add undesired drag.

I want everything!!!!!

I'm also worried about parasite drag... Let's say you use a C-172 for this, you would have cruise at at least 70 - 80 Knots to stay below stall speed in the event the wingboard would create additional drag from maneuvers that would decrease airspeed by more than 20 knots.

Sounds a little crazy, but also fun... However there is no way the FAA will ever approve this for part 91 or 135! Never ever ever ever ever ever!!! Sadly!

Yo Mama's so ugly only Walter White would take her for a ride!!!!

That looks scary... Just a seat and a stick!
