In addition to some relatively "common' types, I saw the following aircraft, only one of which I had seen before [the SE5A, albeit not in a "skywriting configuration]. Enjoy the following pictures. For other [non aviation] photos from the museum, see my World Travels blog.
Top to bottom are:
Short SC1 - the world's first VTOL aircraft, from 1957!
H.S. 125, G-ASSM, designed by Geoffrey de Havilland
Hawker P.1127, first prototype, leading to the Harrier Jump jet
Royal Aircraft Factory SE5A, G-EBIB, with extra equipment for skywriting!
