On November 12, 2011, the Iberia Airbus A321 had been approaching Tenerife South airport at high speed just before it landed on the same runway that a Jet2 Boeing 757-200 was departing did so because of a premature take-off clearance to the 757.
The 757 was airborne over the runway as the A321 touched down at an unexpectedly fast approach. Although the A321’s airspeed had decreased constantly through the descent, its ground speed was 210kt. Expected airspeed is in the 180-203kt range.
The planes were separated by at least 4,100ft.
The incident has been attributed to the tower controller’s “improper handling” of the take-off clearance to the 757.
