How was luck involved in the Battle of Midway?

Answer 1

1. Luck that the US dive bombers found the carriers.

2. Luck that the IJN carriers were loaded with fueling and arming airplanes; no better target could ever be imagined!

3. Luck that the IJN fighters had vacated the high altitudes (which would have gotten the dive bombers) and dove into the attack on the torpedo bombers instead. Another words, the IJN warship's AAA could have shot down the USN torpedo planes without much effort. Hitting the USN torpedo planes with fighters too, simply made the slaughter easier. But they forgot about the dive bombers...and that's what did it!
