A Russian military aircraft thunders into the sky at 4:47 p.m. from Russia's air base at Hmeimim in western Syria, veering to the east.
An observer takes note of all three details, opens a phone app and enters the information into three designated fields.
Fourteen minutes later and 100 km away, Abdel Razzaq sees the aircraft flying over his town of Maaret al-Numan. He opens his own app and types: Maaret al-Numan, Russian military aircraft, headed northeast.
