Jan Zurakowski
There have been a number of references to him on this forum.. .This link provides a good resume of his action packed life.
For those who might be in some doubt as to what his cartwheel involved there is a schematic diagram which explains it.
There is also an amusing reference to his tailslides in a CF100.
