Has Bashar al-Assad's plane crashed? Speculation as Syrian flight disappears mysteriously

Rebel forces in Syria on Sunday seized control of capital Damascus and declared the city "free". This marks a significant milestone in the country's 13-year civil war, bringing an end to President Bashar al-Assad's iron-fisted rule. While the Syrian Army and Prime Minister have issued statements giving over control to the rebels, the President's location is still not known.
