I assume it was flying away from the missile
That seems like an unlikely assumption given that the crew saw the missile from the cockpit.
But because you have castigated and caused to be fired ("resigned", my ass) someone because they dared to express themselves via the previously accepted political process by which people in a democratic society decide controversial issues like this.
Which is democratic process as well. People have every right to participate in the democratic process, just as they have the right to free speech. What they don't have is freedom from the consequences of those actions or that speech. If people, corporations, and organizations refuse to associate with you because of that, that's also democracy at work.
