where to start..
The 1500' heli pilot who likes to take his time on the R/T, telling me where he is, where he's going to (and sometimes why), what he's doing then, and then, before heading back to there.. all these little bits of info broken up with "ummm"s and "ehh"s.
And why does he only ever call when I've someone about to commence an SRA or I've 3 on IF training circuits, etc.
Then theres the lad at the other end of the scale
