Wednesday brought a veritable smorgasbord of "new" information about the Russian passenger jet which fell out of the sky above the Sinai Peninsula last weekend. 

First there was an audio recording from ISIS' Egyptian affiliate reiterating that they did indeed "down" the plane. Next, the ISIS home office in Raqqa (or Langley or Hollywood) released a video of five guys sitting in the front yard congratulating their Egyptian "brothers" on the accomplishment.

Then the UK grounded air traffic from Sharm el-Sheikh noting that the plane "may well" have had an "explosive device" on board.

Finally, US media lit up with reports that according to American "intelligence" sources, ISIS was probably responsible for the crash. 

Over the course of the investigation, one question that's continually come up is whether militants could have shot the plane down. Generally speaking, the contention that ISIS (or at least IS Sinai) has the technology and/or the expertise to shoot down a passenger jet flying at 31,000 feet has been discredited by "experts" and infrared satellite imagery. 

But that's nothing the CIA can't fix.

With the Pentagon now set to deploy US ground troops to Syria (and indeed they may already be there, operating near Latakia no less), Washington is reportedly bolstering the supply lines to "moderate" anti-regime forces at the urging of (guess who) the Saudis and Erdogan.

Incredibly, some of the weapons being passed out may be shoulder-fire man-portable air-defense systems, or Manpads, capable of hitting civilian aircraft. 

But don't worry, those will only be given to "select rebels." Here's more from WSJ: 

The U.S. and its regional allies agreed to increase shipments of weapons and other supplies to help moderate Syrian rebels hold their ground and challenge the intervention of Russia and Iran on behalf of Syrian President Bashar al-Assad, U.S. officials and their counterparts in the region said.

The deliveries from the Central Intelligence Agency, Saudi Arabia and other allied spy services deepen the fight between the forces battling in Syria, despite President Barack Obama's public pledge to not let the conflict become a U.S.-Russia proxy war.

Saudi officials not only pushed for the White House to keep the arms pipeline open, but also warned the administration against backing away from a longstanding demand that Mr. Assad must leave office.

In the past month of intensifying Russian airstrikes, the CIA and its partners have increased the flow of military supplies to rebels in northern Syria, including of U.S.-made TOW antitank missiles, these officials said. Those supplies will continue to increase in coming weeks, replenishing stocks depleted by the regime's expanded military offensive.

An Obama administration official said the military pressure is needed to push Mr. Assad from power.
