It was probably an inevitability: The U.S. Transportation Security Administration is looking to increase security measures in response to the Russian plane crash in the Sinai Peninsula in November, after evidence shows the crash was likely caused by a bomb detonated on board. That includes the airport at Sharm el-Sheikh, where the flight left before the crash.

While the United States does not have any flights departing from, arriving in or flying over the Sinai region, the bomb plot may have exposed some weaknesses TSA is looking to shore up.

All foreign airports working with U.S.-based airlines must comply with TSA regulations, although there is no direct oversight from that body. TSA is currently reviewing their regulations and considering adding heightened security measures at some airports.

The investigation into whether a terrorist plot — potentially orchestrated by the ISIS terrorist network or their sympathizers — brought down Russia’s Metrojet Flight 9268 over the Sinai Peninsula on Nov. 1. The United States is investigating, as are other nations. What actions the TSA would take, if any, remain to be seen, and may further develop as a result of the investigation’s findings.
