My point entirely, lockheed had to install it to make it land safely, if it was so good why didn't Boeing copy it?
I suspect Boeing simply did not have the technical expertise to do so.
In fact, speaking of technical expertise, my local airport neighbor, who parks his GA airplane next to mine, is a retired Boeing design engineer.
His exact words, from a conversation about a month ago...."When we first got a close look at the systems and avionics integration on the L1011, it was a huge wake up call for those of us in Seattle, Lockheed was years ahead of anything we even had on the drawing board."
And, so it goes...someone had to be first.
Lockheed most certainly was, without a doubt.
