I remember another set up where they mounted the plane on a pivot so it would turn with the wind like a weather vane. The rational was it could turn into a bad storm, presenting the smallest, strongest and safest profile. Considering the problems that presents like sewer, water, and electric connections which also pivot, along with the increased cost, I'd hate to think they did it for shits and giggles. I do, however, remember thinking from the statements at the time, they did.
Here's a pivoting set up for sale.
