Design and development
The P.B.9 was a single-seat open cockpit equal span biplane scout. It was powered by a 50 hp (36 kW) Gnome rotary engine and had a fixed landing gear with a tail skid. It was built within a week (giving rise to the nickname "Seven Day Bus") and was first flown August 1914. Although the aircraft performed well only one was built which was later used by the Royal Naval Air Service as a trainer.
