Changed Several Times
ICAO has changed several times.
Until middle/late 90's was "into position and hold" I think was not directly related with Canary Is. accident but changed for some other incident at that time.
Changed to "line up and wait" with "and wait" optional.
it seems to me that every accident/incident that someone find that R/T could have been something to do then R/T must be changed, modified.
Instead of keep it simple, clear and concise is turning to a more build up/just in case/etc etc phraseology.
It will eventually become a plain language R/T asking the pilot "please, describe the clearance once again..."
Worlwide standarization should be THE topic in R/T!
