j2 All of the info. about flaps, altitude, and speed applies to all planes. I think he winged some of it to give the impression that he was an airline pilot. But, trust me, the information he knew about the 727 is info. that can be learned from an aviation magazine, or simply visiting the Boeing plant, doing your homework, etc.
As for laundering: The average bill lasts 18 months in circulation in the US. the only people who were looking for the twenties were tellers in the northwest, and who knows how often. All he had to do was wait six months, fly to the east coast, go to a bunch of banks and exchange twenties for hundreds and he is set. Not to mention the possibility of going to a casino and simply buying chips, and then cashing out. It wouldn't take long to get rid of the money, and nobody is going to questiong you.
I really don't think laundering the money was that difficult. AS long as he did it in another part of the US or in another country, such as mexico, cayman islands, etc.
