Who was never given instructions(headings,speed) by a controller in Europe after some background voices,was given different instructions by another voice?YES training personnel whose decision wasnt the best at the moment.
Would that require a safety discussion?I don't think so.
So for a child to REPEAT instructions given by his father I doubt the controler should be let go for that but given a blame yes.
What I am intrigued about is how easily the pilots accepted and executed such instructions without a sign of doubt.
It has happened that children(england) used some devices to listen and transmit over atc frequencies..So if i ever hear a child giving me instructions in the air and especially on the ground i would enquire into the message given to me..contacting the ATC on 121.5 as a start...
If the FAA blames the ATC, well the pilots too should get one
