Shadow of Flight

Over Columbus Day weekend yours truly received his Hang I rating, the first rating for Hang Glider pilots. I did so flying a Falcon 195.

When the sun is directly over head and the Falcon is on flat level ground, and with its wings level with the Earth, it casts a shadow measuring 195 square feet.

During one flight, when I was about thirty feet off the ground I glanced down at my shadow and thought, "Gulp."

After landing, I wondered, what was the area of the Falcon's shadow when I was thirty feet off the ground? Assume the sun was directly overhead, a level ground, and level plane of flight.
