I did, but I don't have all the answers, and formulas, and figures, at my fingertips any more...
To stir up the discussion, what about a 'breakdown' of the Ekin of a Fieseler Storch (or similar) flying at about 50kts in a 50kts headwind ?
Let's extend this: Headwind 49.99 kts and the Storch is having a collide with a tower, best would be just above a platform.
What would happen: A very gentle little bump against the tower and then the subtle drop/land on the towers' platform. Nothing bent.
