OK - now that I've probably bitten off more than I can chew (travel-wise); I've never flown (not me) with a film camera, let alone a LF camera AND film.
Other than this advisory from the TSA:
"The equipment used to screen checked baggage will damage undeveloped film. Pack your undeveloped film in your carry-on bag. High speed and specialty film should be hand inspected at the security checkpoint. To facilitate hand-inspection, remove your undeveloped film from the canister and pack in a clear plastic bag."
Uh, sheetfilm no have' um canisters
I would drive but I only have one day of travel time. It would take me 18 hrs. one-way, so it looks like I'll be paying a 2nd visit to ye honorable TSA guardians within two weeks.
HEY! -- DON'T TOUCH MY JUNK!
