In view of the stronger capability of Islamic extremist groups to launch more terror attacks in different parts of the world, the global aviation industry is not taking possible security threats lightly. One such "threat" was a Wi-Fi network named "Al Qaeda Free Terror Network" discovered by a London-bound US American Airlines passenger on Sunday.

The traveler, who boarded the jet in Los Angeles, informed the flight crew of the discovery. It led to the plane being ordered by aviation authorities to go back to the gate for investigation.

Police probers, however, could not find any evidence that the Wi-Fi network came from either passengers or flight crew. Their theory was that it was an active hotspot from someone in the airport terminal, not necessarily inside the aircraft.

Besides the investigation that delayed the plane's departure, the crew also encountered a maintenance issue while the flight personnel have reached their time limit and needed to be replaced by a fresh crew. The plane was rescheduled to fly out of LA on Monday afternoon, according to NBC.

The one-day delay angered some of the passengers on the same flight. One traveler named Anthony Simon tweeted on Monday afternoon, "Thanks to the idiot who did this meaning I won't get back to London for another day." However, Simon was not clear if he was referring to the fellow passenger who discovered the hotspot or the person who named his Wi-Fi connection after a terror group associated with the Sept. 11, 2001 attacks in New York.

According to the Sydney Morning Herald, similar incidents in the past had caused flight postponements or delays.

It cited the diversion of a Southwest Airlines plane headed for Denver to Seattle after passengers discovered two hotspot names that sent chills down the spine of travelers since the trip coincided with the anniversary of the Sept. 11 bombings. The names were "Southwest Bomb on Board" and "Bomb Location Seat 19E."

Not all Wi-Fi names, however, are spine-tingling. A survey made in 2012 by Fairfax Media of hotspot names in Melbourne found names that range from funny to racist. Here are some examples: "Handsofmywifi," "House of Awesome," "White Supremacy" and "YourKidsAreUgly."
