In this thread:
https://goscf.com/t/25269 I wrote to clarify/correct a misleading book quotation regarding the design of the 1913, 20 cent, Q-8 Parcel Post Stamp shown carrying mail, "
Prior to regular government airmail routes which began as noted in 1918 there were mail carrying flights know as pioneer airmail. One such pioneer flight beginning 1-13-1913 2:12 P.M. carried the first parcel post packages (beans) by air from Boston en route to New York City. The pilot was 22 year old Harry M. Jones flying an airplane he built. This trip with carriage of parcel post matter was commissioned by the USPOD.
Official Air Parcel Post did not begin until 35 years later, first international then domestic."
The first pioneer flight, of 97, (means USPOD associated with carriage of the airmail) was set in 1910. So by 1912 when the 20 cent Parcel Post was designed, airplanes had carried mail. Otherwise if you had a plane and wanted to for fun, carry mail to the post office, nothing stopped you if there were trusting souls who though they would not mind if you crashed and burned their mail.
It was an older thread which I bumped but at which time I did not have the photos posted below to add. The "edit time" had timed out to edit that post with these photos. So here they are in a new thread with now appropriate title.
