$2.4 billion in $100 bills to Baghdad

It weighed 28 tons and took up as much room as 74 washing machines. It was $2.4 billion in $100 bills, and Baghdad needed it ASAP.
The initial request from U.S. officials in charge of Iraq required the Federal Reserve Bank of New York to decide whether it could open its vault on a Sunday, a day banks aren't usually open.
"Just when you think you've seen it all," read one e-mail from an exasperated Fed official.
"Pocket change," said another e-mail.
Then, when the shipment date changed, officials had to scramble to line up U.S. Air Force C-130 cargo planes to hold the money. They did, and the $2,401,600,000 was delivered to Baghdad on June 22, 2004.
It was the largest one-time cash transfer in the history of the New York Fed.
