Yes, it was. Planes are very reliable. What's the odds there's a crash in Iran hours after they attach the US and are on high alert for a counter attack?
It's a safe bet.
I'd assume the odds of a country shooting down an aircraft that took off from their own airport ought to be pretty low as well.
Sure. Sydney Airport on a pleasant summer afternoon? Odds so close to zero that it doesn't matter. Tehran Airport at what could be the start of a war with the US? If I were an insurer I'd be pricing that risk _way_ differently.
Most major airlines suspended flights to and from Teheran on that day, so the odds were a bit higher than normal.
Not a “safe bet.” Reasonable assumption yes but no more. An American Airlines planet crashed only a few weeks after the September 01 attacks, but it was just an actual accident.
No, this is not chance of a crash anywhere, it's that a crash happens in Iran where there just aren't that many flights. Even more on this day when many airlines suspended flights. The math here is probability of air crash times number of flights in Iran, it's such a low number that one would be silly to think it's a coincidence.
