[AP] VIRGINIA - Authorities investigate threat found on plane
CHANTILLY, Va. Federal authorities are investigating a threatening message found inside a plane at Dulles Airport.
Officials tell W-J-L-A T-V that the message was found last Saturday, on the wall of a cargo hold of a United Express plane.
The message read -- QUOTE -- "Plantation Toby says Osama bin Laden and younger bro Ali Hasseem is my hero...bombs away Mr. Bush...Welcome to plantation airlines."
United Airlines has released a statement saying it is taking the message seriously, and that United doesn't suspect the message posed any threat to the airline or its passengers.

Interesting note on that airplane, it appears that there is a Plantation, Florida.
Toby may be from "Song of the South".
or
A Commander in the Irish Army.
A slave for one thing.

Note the OSama bin Laden News, it looks like it is a note that says French instead of Plantation airlines, I noticed
it on the plane search and thought it was the same, but the 4th one on this page, shows French.....

You would think United would wonder who is getting into the cargo holds of their planes.
