For those of you wondering why or why not a “No Fly Zone” in Ukraine might be a good idea, I have a discussion of that by two knowledgeable individuals HERE.
One of the people is Ward Carroll, an ex-navy F-14 RIO (radar intercept operator). He has a fairly interesting You Tube channel that mainly discusses various aspects of Naval Aviation. They discuss in great detail what can and cannot be done to aid Ukraine while simultaneously avoiding things getting out of control.
