Dear Mr. Simplex -
Here's a USGS topographical map of the area with 5 foot contour intervals (click on it for a larger version). I made it just for you.
As you can see, all of the Dec. 17, 1903 flights, including the longest 852 foot flight shown by the red arrow, started and ended in the middle of a very large planar area located between the 10' and 5' contour lines.
I accept your apology.
