Perhaps some extra seconds but …

An Airbus can cover 11 miles in approximately 10 to 11 seconds, 
as most jet airliners cruise at about 450 knots 
(approximately 518 mph or 740 ft/sec).

I calculate a little over a minute to traverse 11 miles at that speed. Still better to take action before it gets too close.
