Thank you. 1 nm = 1.852 km. So corridor was 14.816 km wide. The ultimate crash site being outside the corridor is conceivable.
I ask because I was thinking about corridors over Syria and Afghanistan. Which I understand commercial airlines still fly over between Europe and South East Asia?
More advanced surface to air missile capabilities extend to FL100 (100,000 feet).
While the Pilot In Control has ultimate discretion I suspect airline policy plays a strong part in the ultimate routing given fuel consumption and flight time considerations.
If helpful to others in their choice of airline: flightaware shows flight routes.
