The very same EgyptAir jetliner that crashed into the Mediterranean Sea last week was once vandalized with graffiti reading “We will being this plane down” according to the New York Times.

The Times quaintly (and perhaps naively) calls the graffiti connection an “eerie coincidence.”

In an eerie coincidence, the EgyptAir jetliner that plunged into the Mediterranean on Thursday was once the target of political vandals who wrote in Arabic on its underside, “We will bring this plane down.”

Three EgyptAir security officials said the threatening graffiti, which appeared about two years ago, had been the work of aviation workers at Cairo Airport. Playing on the phonetic similarity between the last two letters in the plane’s registration, SU-GCC, and the surname of Egypt’s president, Abdel Fattah el-Sisi, some workers also wrote “traitor” and “murderer.”

This report brings into question the screening process for any airport personnel in Egypt, especially following last years’ downing of a MetroJet  which originated out of Egypt and Reuters has reported that an EgyptAir mechanic has been detained in connection with the terrorist act.

“After learning that one of its members had a relative that worked at the airport, Islamic State delivered a bomb in a handbag to that person,” said one of the sources, adding the suspect’s cousin joined Islamic State in Syria a year and a half ago.

“He was told to not ask any questions and get the bomb on the plane.”

Another source said of the other suspects: “Two policemen are suspected of playing a role by turning a blind eye to the operation at a security checkpoint. But there is a possibility that they were just not doing their jobs properly.”

According to the Telegraph, French investigators are still concerned with some of the airport personnel in Paris as well as some of the other stops this plane made on its fateful last day:

Last December around 70 red badges were withdrawn from staff at Charles de Gaulle who were found to have praised the attacks in Paris, prayed at mosques linked to radicalism or showing signs of growing religiosity like refusing to shake hands with women.

A French trade union also warned that short stopovers like that made by Flight 804, which was on the ground a little over an hour, gave little time for security staff to carry out.

The investigation into last week’s crash continue today, including the deployment of a submarine to search for more wreckage. The troubling news of radical Jihad behavior from ground personnel at airports should call into question the standard screening and monitoring procedures for any worker who has close access to passenger jets.
