Urban Myth or not?....
A much related 'story' when I was a 'sprog' at BK on 'Chippies' all those years ago....
An EW pilot who used to stutter a bit, and subsequently supposedly held back in his promotion to Capt. because of the stutter,
in 'those' days, told to call SY TWR passing abm Broken Bay.
Said to have emulated the sing-song SYDNEY FLOUR Radio Commercial of the time...
"S-Sydney Tower is our t-tower, w-we use it every d-day,
And this is EWA, and I'm abeam of B-Broken Bay".
'Busted' back to F/O, for a while, so was the tale....
