EgyptAir Flight 804 disappeared from the radar, and experts suggest that an act of terrorism could have brought down the aircraft. Now, everybody is asking if it is a 9/11-like attack.

The plane was carrying 66 people from Paris to Cairo. It went missing early Thursday morning and prompted an international search.

If the entire ordeal is a terrorist attack, it certainly reminds people of 9/11, says IntelNews.org.

It has also been said that if the disappearance is an act of terrorism, then it could mean that a militant group has been able to defeat the most stringent airline travel security measures in all of Europe.

American and European intelligence agencies, including France’s own DGSE, have served repeated warnings in previous weeks. According to them, the Islamic State was preparing for new attacks, and that France was their main targeted.

The group has been keeping quiet since early this morning when it was announced that EgyptAir Flight 804 has disappeared. However, it is also known that the group waits for a long time, sometimes for days, before taking responsibility for high-profile attacks.

According to CS Monitor, Egyptian security officials have stated that they were doing background checks on the passengers to see if any of them are connected to extremist factions.

The chief of Russia’s Federal Security Service, Alexander Bortnikov, has said that the disappearance is a terrorist attack.

It was just last year when Russian Metrojet Flight 9268 was toppled from Egyptian airspace. The responsibility was claimed by the Islamic State terrorist group.

“If you analyse the situation properly, the possibility of having a terror attack is higher than the possibility of having a technical fault,” Egypt’s aviation minister Sherif Fathy said.

According to CNN, US officials are also claiming the previous theory that a bomb explosion could have caused EgyptAir Flight 804 to crash.

The possibility of such a terrorist attack could make vehement and massive changes in the international airline industry. The global airline industry is already faltering from all kinds of financial and administrative pressures in the post 9/11 era.
