Interesting about "back up on the hill".
It is interesting, but hardly surprising since this interview is from 1927, many years afterward and when Mr. Daniels was advanced in age, and given the fact that for MANY years before the 17 December 1903 flights that began on a horizontal rail, including the 14th I believe, John T. Daniels and the other Surf-men frequently helped the Wrights launch their gliders and earlier powered planes from the hill.
The proof of the 17 December 1903 flight from the horizontal rail is in, among others, Mr. Daniels' famous photo.
