Of course after the AEFs converted to the Bulldog 2 Chipmunks WP 833 and WP 962 continued in RAF service and flew around the world. They were piloted by Ced Hughes OC 5 AEF, Bill Purchase OC 7 AEF and Tony Cowan a No 5 AEF pilot. Two books were published about this adventure "Around the World at 90 knots" by Bill Purchase and "Chipmunks Around the World" by Tony Cowan. Both are now out of print, but if you can track them down on eBay or on Amazon they are well worth a read and cover one or 2 'interesting' moments!
