According to a letter from the government of Turkey to the Secretary General of the United Nations, a Russian fighter jet was over Turkish airspace for a mere 17 seconds before it was shot down.

The letter, published by Wikileaks, claims two planes “at an altitude of 19,000 feet, violated Turkish national airspace to a depth of 1,36 miles and 1,15 miles in length for 17 seconds from 9.24′.05″ local time.”

“Following the violation, plane 1 left Turkish national airspace. Plane 2 was fired at while in Turkish national airspace by Turkish F-16s performing air combat patrolling in that area in accordance with the rules of engagement. Plane 2 crashed onto the Syrian side of the Turkish-Syrian border,” the letter concludes.

Observers were immediately skeptical of the letter’s assertions.

“Basic math shows that plane was supposedly flying at 391km/h for it to travel for 17 seconds. SU’s max speed is 1320km/h,” Jonas Olov Eriksson says.

“17 seconds for WW3…well done Turkey,” according to Dave Cranfield.
