Not one significant one YET. And that's my whole point. 20 years history is meaningless today. The landscape has completely changed - almost completely.
And BTW, PTSC has turned a profit in the past, I believe, albeit a meager one (contracts with the USN for sub-based SONAR). But it is meaningless today as well. And if PTSC had turned a big profit frequently in the distant past, that too would be meaningless today, and more importantly, tomorrow.
I think we continue to agree to disagree.....and there is nothing wrong with that!
