I think it pure insanity to have departed under those conditions. Put me in jail if you want but I’m staying on the ground.
I avoided trans-oceanic routes in the latter part of my career... seniority has its perks.
But if I were still doing international flying, I would draw a 1000 mile border around the edges of Syria, Iraq, Iran, Pakistan and Afghanistan. Fire me of you want but my airplane doesn't enter that area.
