Many years ago in the middle of the Indian Ocean on a very hot and bumpy night we could hear a female Australian voice trying to pass a position report to Colombo on H.F. The call-sign sounded like "Qantas Tin". After about fifteen minutes of being repeatedly stepped on by Madras, Bombay and Singapore and having her signal fading out and coming back in again she eventually got her message through. Loud and clear a very superior British voice said "Good on you, Sheila!". "Up your arse, Pom" was her immediate response!
