Curtiss HA-1 was designed by Captain B L Smith of the US Marine Corps as a two-seat patrol fighter floatplane and built by the Curtiss Engineering Corporation. A-4110 is seen here probably at the Rockaway Naval Air Station in December 1918, it was eventually written off after it caught fire in the air, the pilot (Roland Rohlfs) managing to land safely. The fuselage was wood with a fabric covering it was powered by a Liberty 12 engine. Scanned from an original reproduced photograph from my collection date, and photographer unknown.

Photo taken during the first flight from Egypt to India. It appears to be in what is now Pakistan, probably Karachi, although the flight continued on to Kolkata. It had been intended for an O/400 to fly from the UK to India but the initial aircraft went u/s at Heliopolis. It was then planned to fly on to Australia - the pilot was Australian Ross Smith - in 1919. However, while Smith headed off to survey a route, C9700 was commandeered by the military in India to bomb Kabul. It was wrecked in a wind storm at Risalpur before Smith returned.
