That crew
up - end of story.
You're right, they did.
But there's a catch emerging from this thread. You'll see Pprune used as a weapon more often in the future, instead of the proper channels, and it can affect any of you.
So, next time you see a crew acting like these cowboys, just say:
"Yes YOU DO! and you better de-ice or I'll drag yer arse through Pprune big-time"
