Miscellany notes regarding patents in the hang gliding universe:

For those who find futures in the past: I assembled a tight copy of the filed-in-1892 patent by Louis P. Mouillard titled Means for Aerial Flight. Appreciate that he studied bird flight for some thrty years, that Otto communicated with him, that Chanute credits something to him, that wing warping and ailerons may have been well installed in the patent's instruction, and more. Ultimate interactions with the early seeders await careful examination of primary documents---a process still ongoing, as strongly noted by Tony Prentice and Stephan Nitsch. Savor the ideas and language; see if some future is in that past yet. See: Means for Aerial Flight
