The Transportation Security Administration put out an advisory April 20 warning aircraft owners about a message, posted in Arabic on a Web forum, that explained how to identify private American airplanes.
“Destroy private American aircraft…We call upon all Muslims to follow and identify private civilian American aircrafts (sic) in all airports of the world…It is the duty of Muslims to destroy all types of private American aircrafts (sic) that are of the types Gulf Stream (sic) and Lear Jet (sic) and all small aircraft usually used by distinguished people and businessmen,” the translation said.
TSA advised “general aviation aircraft and airport owners and operators” to review the security guidelines in its own and AOPA Airport Watch publications, and to report any suspicious activity to local law enforcement and the TSA hotline (866-427-3287).
