Whoa there chaps. I read the OP as a request for info on how to pass on a concern.
Jumping on him with stern warnings seems a tad harsh imho. I'm sure the spotters on the Newall Rd viewing platform aren't having their collars' felt on a regular basis. Nor the thousands visiting the Manchester Aviation Viewing Park where it's impossible to avoid hearing transmissions.
TCTC pm me and I'll give you some names and numbers.
