Why did you need a "good" way? :)

I think anyone who carries that much coin thinks about it whether they admit it or not. I used to fly JFK to ANC and we'd carry hundreds of million in cash (destined for Bank of Japan). You have a lot of time to brainstorm with 10 hours of fuel, and that much cash. What killed us is that they always loaded it just behind the smoke curtain, so you could see it.

Hey Mike,

Thanks for gettin my play money to the bank safely :-)

Nothing overly crazy, but I have seen some pax try to bring some crazy stuff onboard before... All of this stuff made it through security at some point or another and was carry on/planeside checked (or refused):

Fully Stocked Dorm Fridge (sandwiches and beer)
Fullsize gas operated Snowblower
Moped
2 cases of Weather Balloons
Large crate of saran wrapped pornography

I just flew a Mercedes convertible out of the Middle East. Them boys there have some cash.

A little extra thrust
 

Used to have a semi-regular run to take Minuteman missiles to the depot and back to the silos. 89,000 lbs of class B explosives.

Formula 1 cars to Japan. I cannot confirm nor deny any pictures taken......:p

A C-5 full of Christmas trees and M&M's for our troops in Mogadishu.

The entire field of the European Grand Prix motorcycle teams.

247 Zaire workers from Luanda, Angola to Kinshasa, Zaire when the civil war started up again and they were in line to be rounded up and executed...what made this interesting was that this was in a B-727/100F outfitted with fuel tanks in the cargo area...these folks were anywhere and everywhere including on top of each other...ah, those weren't the days...

2 windshields
Penguins
2 Dolphins

All seperate flights on a 727
