My first simulated impact was a direct hit by a 10 mile iron asteroid. I dropped it 2k miles away (California from where I'm at) and the fireball was hot enough at my position to set my clothes, my house and the local woods on fire. Then a couple hours later came a 1,300 mile/hr wind that blew the fires out. I don't expect I'd survive that.![]()
