Some of the early airmail planes couldn't even reach 10,000 feet. e.g. the JN-1 had a ceiling of 6,500 ft.

- aidenn0 4y agoHow did airmail cross the continental divide?
- Oxidation 4y agoThe first trancontinental routes crossed via Rock Springs (6388 ft) and Rawlins (6834 ft). It's not immediately clear to me which planes they used, but that's over the Curtiss JN-4B service ceiling. The route was originally surveyed in 1920 by 3 cutting-edge Junkers-Larsen JL-6s, an American-built F13 (only 8 JL-6s were ever made!). Bert Acosta flew one of them.
