If I can go to anywhere in time

I wish I could go to time where manhattan project was going on, so I can see the nuclear bomb explosion and hear famous quote. Also I could learn how the nuclear bomb is so deadly. I wish I can go to Jerusalem when there was Jesus, so I can see him. ( I was wondering how he looked like.) I wish I could go and get a ride in a bomber at WWII. So I can drob 400lb bombs on the germans or allies. And Last place I want to go is vietnam during Vietnam war, so I can know why you get vietnam syndrome.
