Many moons ago I was ferrying a new aircraft from the UK to Oz and we had an overnight at Mumbai (India)(It was Bombay back then). It was a Sunday morning as we departed and climbed out towards Calcutta in fine weather. We transferred from departures to area on VHF and as we approached our cruise level, control said:
"call-sign, report when you loose contact"....
We looked at each other somewhat speechless until we got ourselves together and made an acknowledgement! Turns out he was wanting to prompt us to transfer to HF.
