1001 Crash - The Tenerife disaster - Two Boeing 747 collided Website in English Site en français

The Tenerife crash - March 27th, 1977

The controller was struck by a sudden doubt. He reminded the KLM captain that he had not been cleared for take-off.

17 :06 :20 (Tenerife control tower) : Stand by for take-off, I will call you.

17 :06 :20 (PanAm first officer) : And we're still taxiing down the runway, the clipper one seven three six.

The last two messages were radioed simultaneously and were therefore heard as a long four-second high-pitched sound. The KLM 747 speed increased. Some 1,500 meters further on, the PanAm 747 was still taxiing down the runway.

17 :06 :25 (Tenerife control tower to the PanAm 747) - Roger alpha one seven three six report when runway clear

17 :06 :29 (PanAm first officer) - OK, we'll report when we're clear

17 :06 :30 (Tenerife control tower) - Thank you

The KLM captain did not react. He may have misunderstood and thought that the PanAm 747 had just cleared the runway.

17 :06 :32 (KLM first officer) – Is hij er niet af dan? {Is he not clear then?}

17 :06 :34 (KLM captain) – Wat zeg je? {What do you say?}

17 :06 :35 (KLM first officer) – EstIs hij er niet af, die Pan American? {Is he not clear that Pan American?}

17 :06 :36 (Angry KLM captain) – Jawel. {Oh yes. - Emphatic}

Meanwhile, the PanAm jumbo jet reached the fourth taxiway. Suddenly, the PanAm captain spotted the landing lights of the KLM Boeing approximatively 700 meters away in the fog.

17 :06 :41 (PanAm captain) – (screaming) He’s coming… look… this son of b**** is coming

17 :06 :41 (PanAm first officer) - (screaming)
