Geography is a lesson best learned in school at GL, not at FL320 and is best taught by a teacher. Failing that I have always found Google Earth to be very good or, as Guppy says, an atlas is a very good standby. If anyone is interested in the physical features of the land they are flying over they will have done at least a little research but most don't even know how to say please or thank you and that is when they are on the way back.
"on the left you will see the - oh sh*t, the no 1 is playing up, NO DONT PRESS THAT. Bugger, its gone, well it was a range of mountains and I got distracted looking up the name. On the right is a large expanse of water with an interesting hist..... What do you mean the no 2 is looking dodgy? I SAID DONT PRESS THAT. I'll have to get back to you on the geography thing...."
And that is if you could make anything out over the PA, most of it sounds like it is spoken backwards in Greek with marbles in the mouth and a bucket over the head.
Not a good idea.
Awaiting incoming.
