This is significant as these drones are very slow flying and require a great deal of pre-flight planning and set up to get a mission off the ground. They are very bandwidth intensive and to have one in the air and then a reserve vehicle coming in at just the right time as replacement smells not of extensive planning but more of a premeditated plot!
The Obama administration removed a well-armed, 16-member security detail from Libya in August, The Wall Street Journal reported last month, replacing it with a couple of locals. Mr. Stevens sent a cable Aug. 2 requesting 11 additional body guards, noting "Host nation security support is lacking and cannot be depended on," reports Peter Ferrara at Forbes.com. But these requests were denied, officials testified before the House Oversight Committee earlier this month.
Based on documents released by the committee, on the day of the attack the Pentagon dispatched a drone with a video camera so everyone in Washington could see what was happening in real time. The drone documented no crowds protesting any video. But around 4 p.m. Washington received an email from the Benghazi mission saying it was under a military-style attack. The White House, the Pentagon, the State Department and the CIA were able to watch the live video feed. An email sent later that day reported "Ansar al-Sharia claims responsibility for Benghazi attack."
