If I wasn't the shy retiring type that I am (quiet at the back there!), and we were anywhere near JetBlast, I'd maybe put lurid interpretations on the
who wants me to take her up to do some aerial stuff
bit.
There are people like formationfoto who I am sure will offer oodles of techie toggie stuff, but from experience (and the fact that I know someone local who does aerial toggie work in C150 / 172s), there's no problem. There are some who just lean out of the window and do it that way, or you can prop the window open. I don't think the 172 is approved for flying doorless, but I doubt you really need that. Go for it and hope you get into the 1500 ft high club!!
