Round up the usual suspects.  Isn't this a bit early?  April 1
is more like it.  Obviously the passenger was playing a Killer CD.

If the McDonnell jets are so sensitive to EMI that a CD player
(!!!) can stand one on its ear, better not fly one within
sight of FM or TV towers, satellite dishes, radar beams, CB
antennas, taxicabs, let alone any source of lightning discharge.
Confiscate all cellular phones in checked or carry-on luggage.
If a CD Walkman can crash a DC-10, think of what a megawatt UHF
TV station would do.

And don't forget, digital watches use RF energy.
