Should we be seeing more Yankees in 1984?
And, I gather that near-ice activity wasn't so much a capability at the time. Moving in the ice flows would take longer than simply zipping down and through the GUIK gaps to the Atlantic, but safer. Was it that sonar was just not up to the task operating in the ice flows of north end of the Denmark Strait?
I guess these are analytical questions towards the '68 to '84 timeframe scenarios.
If I was a Yankee skipper, I would have attached a fishing motor to an iceberg and let it tow me silently to the US East Coast.
