Tenerife was one of my first CRM day case studies. It stayed with me that 25 seconds before KLM rotated into PAN AM the latter called to KLM we are still on the runway. Crossed transmission resulted in call being missed...so for me I will always stay with Tower and if that upsets the ground controller it is unfortunate. Does anyone have a link to the above ICAO procedure that states aircraft on a live runway should remain with Tower?
