LOS ANGELES (CBS) -- Federal agencies were working with Southwest Airlines on Thursday to determine who has been vandalizing their aircraft with mysterious markings.
KNX 1070 investigative news hound Charles Feldman has learned that since February, several Southwest jets have been vandalized with mysterious writings that show up on the underbelly of their 737 passenger aircraft.
The writings -- which some have interpreted as being either Arabic or Arabic-type symbols -- appeared to have been done with a chemical process that reveals the text once an auxiliary power unit is turned on and heats up the outside skin of the aircraft, according to Feldman. |
