NOTE AAMC 20a to 20ll "EXPERIMENTAL FLIGHTS"
The MANILA - SAN JOSE, MINDORO - MANILA flights conducted from early 1928 to middle of 1929, and listed by AAMC or should I say listed by Bruggmann as "EXPERIMENTAL FLIGHTS" were either pilot trainning flights or flown to ferry military officials to and from a rest & recreation facility established by the U.S. Army Air Corps in Mindoro Island. Majority are Bruggmann prepared covers and with conviction I state that they were done so with money in mind. The flights are still worthy of documentation but I believe they should not be in the main catalog list but belong in the "back of the book" list.
