Just what the thread title says. Is it because a lot of US mail is carried on commercial flights?
I know it goes back further than that. Not sure exactly how far, though.Oh that's all kind of what I thought. Could it also be part of the response to the ValuJet crash back in the 90s when the O2 canisters in the hold ignited and brought the plane down?
I've always just used UPS ground, never had an issue, I was just curious about USPS.
You can't ship booze?? OOPS...And I didn't even do that intentionally. The time two of my friends and I smuggled Listerene bottles full of vodka dyed green onto the cruise ship we went on for spring break in college, yea...that was intentional!Same reason why you can't send firearms, booze and a whole list of other things...... Its a postal regulation is all......
