Someone is unwilling or unable to do an internet search to locate a source for a pretentiously-named chunk of blank paper, and we’re not allowed to take the piss? Forget what PPRuNe is coming to. What is the world coming to?
My logbook’s a school exercise book, named Loggie McLogfacebook with a picture of Biggles pasted on the front. You’re more than welcome to poke fun at me.
BTW: If you want a really thick - sorry, I mean really professional - logbook, buy a loose leaf binder of that thickness and fill it with loose leafs. Job done.
