That is NOT what Mr. Pointy is for

Man tried to hijack, crash Qantas plane:
A man armed with two sharpened wooden stakes tried to hijack and crash a Qantas domestic jet with 47 passengers aboard shortly after take-off from Melbourne today, authorities said.
The 40-year-old man stabbed two flight attendants and injured two other people before he was overpowered by crew and passengers aboard QF1737. He was in custody tonight.

In response, Homeland Security Director Tom Ridge announced that Sarah Michele Gellar will be banned from all flights in the United States.
