Thank you - but the question was for caz. Personally I'm not sure a 'self let down over the sea until vfr' would have been a particularly wise option then, do you? Hmm, let me see, cloudbase around 800'? MSA over the sea - 2000ft I believe???? I can hear the reviewing officers now. I wonder - would they have approved that or would that be 'negligent'? I wonder if the radalt on the Mk II was even actually approved as a navigation instrument at the time?
