G-BIAZ

A Cameron AT-165, serial number 400, named Zanussi. A Roziere balloon, the hot air element was first flown on 20 June 1978 at Bristol, Avon. 

Roziere balloons use a combination of helium and hot air. Below the spherical helium gas cell is a conical sleeve where air can be heated by burners in the same way as a normal hot air balloon. By varying the hot air temperature, altitude can be maintained without having to release helium or drop ballast. The burners are principally used to compensate for the lack of solar heating at night. 

30 July 1978 Don Cameron (pilot) and Chris Davey flew from St Johns in Newfoundland in an attempt to cross the Atlantic, but due to a small tear developing in the helium cell, ditched in the Bay of Biscay. They flew a distance of 3,339.086 km in 96 hours 24 minutes, a British and World Roziere Record for AM10 to AM15 class.

G-BIAZ was converted to hot air only, in 1979. Logbook not held by BBM&L. Total hours flown 114.
