Why did no one follow them to see where they were going?
The United States provided ten armored vehicles to the United Nations to support UN and OPCW efforts to verify and destroy Syria’s chemical weapons. The Department of State’s Nonproliferation and Disarmament Fund paid $1.55 million for the ten armored civilian vehicles and coordinated with the Canadian Armed Forces (CAF) to arrange their transportation and delivery to the UN. To further support this effort, the United States arranged for the use of Joint Base Andrews (JBA) as a launching point from Maryland to Lebanon, while Canada contributed the use of a Royal Canadian Air Force (RCAF) CC-177 Globemaster III aircraft from 8 Wing Trenton, Ontario, to airlift the vehicles to the Middle East. The vehicles were flown on two separate flights starting Thursday, October 17, and concluding Sunday, October 20 when they were accepted by the UN.
And what if their destination is 500 or 10000 miles away?
