Obviously, none of us know the percentage of truth/elaboration in this "story". Layman's thoughts:
- ATC are very busy - how did they find a spare man to deliver a dressing down
- Is an over the air dressing down ever appropriate, especially delivered to a trainee pilot - why not just sort the immediate problem and leave the aftermath for later?
- oh yes, lastly....... did it really happen? The pilot concerned is noticeably absent!
