(JNS.org) After the disappearance of Malaysia Airlines Flight 370, Israel has decided to tighten security standards for any flights that enter its territory. Since current suspicions on the fate of the missing Malaysian plane center heavily on a potential hijacking, Israeli security and aviation officials decided to require all foreign airlines approaching the Jewish state to identify themselves much earlier than what was previously required, Israel’s Channel 2 reported. The officials also came up with other new security regulations that remain classified, according to Reuters.

The former head of global security for the Israeli airline El Al, Isaac Yeffet, told the Times of Israel that he believes Iran may be behind the disappearance of the Malaysian plane. “What happened to this aircraft, nobody knows. My guess is based upon the stolen passports, and I believe Iran was involved… They hijacked the aircraft and they landed it in a place that nobody can see or find it,” Yeffet said.

But Lt. Col. (Res.) Eran Ramot, a former Israeli Air Force fighter pilot and currently the head of aviation research at Israel’s Fisher Institute for Air and Space Strategic Studies, said it is far more likely that the plane was hijacked by its own pilot. “It would be very complicated [for someone other than the pilot to have flown the plane],” Ramot said, since reports now indicate that the plane made a

U-turn from its planned route and that its tracking systems were completely shut down. “It takes somebody that knows how to operate an airplane like this,” he added.
