The ISIS back from the plane crash of EgyptAir it? What are the questions created?

With the thriller on whether found or not the wreckage of the fatal aircraft of EgyptAir continues, what is really bothering you.
the authorities of Egypt and not only is it ultimately due to the crash of the Airbus A320.
This is a terrorist attack and who’s behind this? In this eventuality converge almost everyone, without, however, exclude nothing, and look as responsible members of ISIS who acted either in Paris or in Cairo.
The Airbus A320 with 66 passengers on board including seven crew members, three security guards, 30 Egyptians, 17 French nationals as well as citizens of Iraq, Saudi Arabia and other countries took off from the Charles de Gaulle airport.
The crew of the aircraft, which was manufactured in 2003, was highly experienced with thousands of flight hours of the captain and the coalition, while the company owner argued how not transported hazardous materials, or anything else beyond the usual.
From the moment I confirmed how the flight MS804 crashed, he the Egyptian minister Sherif Ismail said that the possibility of terrorism can not be ruled out, stressing that the aircraft have not sent any distress signal, something that is confirmed and the representative of the Armed Forces.
Followed by many similar declarations, from Egypt, France, the USA and other countries, which are not excluded i.e. the possibility of a terrorist attack to such a degree that it’s almost certain that something like that happened. The pronews.gr was the first site in Greece that was an act of terrorism.
The testimony of the captain of the merchant ship allegedly stated how the point lost the trail of the aircraft saw a ball of fire enhances the possibility of explosion in the air of a ticking time bomb and this is the cause of the fall of the aircraft.
The secret services of Israel speak directly to a terrorist attack by ISIS by only question that placed the bomb. The airport of Paris or Cairo. Reminiscent of the incident that had happened last October with the Russian Airbus A321 that took off from Sharm Al-Sheikh and the explosion in the interior of the cabin by an improvised explosive device caused the death of 224 passengers.
“One of the main questions of the research of the last aviation disaster is if the explosive device was placed in Cairo or Paris. If this happened in Paris, will raise the issue of whether a core of the ISIS infiltrated the ground crews at Charles de Gaulle airport. If confirmed, it would be a serious escalation after the terrorist attacks in Paris”, reported sources of the Israel Debka.
The same sources add how this is a further sign of escalation of the terrorist attacks of ISIS in European airports, since it’s the second within three months at the political goal of aviation after the blow to the international airport of Brussels last March, where 31 people were killed and about 200 were injured.
If, however, establish how the bomb was placed in the plane in Cairo, before leaving for Paris, would mark a serious and dangerous escalation of the penetration and operational capabilities of ISIS in the egyptian capital, and a major threat to the stability of the regime of Abdel Fatah al-Sisi.
Be that as it may, however, the new terrorist act has caused fear around the world that was going to travel with airplanes. And this is the goal of the ISIS. This is yet another vindication of Russia wanted in the first place to finish with the terrorist organization created by the U.S., Turkey and Saudi Arabia.
