The statement also says that they "took a more
southerly route in order to avoid the restricted airspace over camp
david",
but its kinda unbelievable because the direct route was right over DC. To
get into camp david they would have to fly a lot more west that they
needed
to get to the airport in NC.

I looked at that too.
In 0.24 seconds Googleing "DC ADIZ TFR Camp David Prohibited" gave me
http://www.faa.gov/avr/afs/afs800/docs/tfrweb.pdf
as it's #1 return.
This guy went on and on about how he checked so many websites about weather
and such, even the AOPA web site. If he was so worried about the Camp David
P area, he could have found the FAA TFR pdf as easy as I did, and if he
would have, he would have saw the list of requirements not only to enter the
ADIZ, but the intercept procedures as well.
