History
The P.B.9 used a set of wings obtained from Radley-England and was designed, built and first flown within 9 days, in August 1914. Its designer claimed it took a week, which gave rise to the nickname "Seven Day Bus".
Variants
Only the prototype was built. It was powered by a 50 hp Gnome rotary engine taken from the company's prototype P.B.1, although the design allowed for an 80 hp Gnome.
Where you'll see it
Although the aircraft performed well, only the prototype was built. It was later used by the Royal Naval Air Service as a trainer.
