Alas my much loved, once dark green book cover licence from the Department of Transport in 1957, is moth eaten, roach nibbled and been thru the wash a couple of times . The signatures of the Director General of Civil Aviation have long since faded away. My signature in the Student licence is almost gone, too...an historic sample relic of teenage scrawl. I even crossed out 'British nationality' and overwrote AUSTRALIAN, as born and bred.
In some distant past, Spin Recovery was crossed out by some bureaucrat because that's just not done anymore. A "safety" measure of course ! How many stall/spin fatalities since, I wonder
A data chipped plastic card with face pic and continuing "security clearance" that fits in a normal wallet SHOULD be the go. No problem for Drivers Licence issuers...but for CAsA ...???
