Yes we are missing one thing...
... in reality they had only ONE CHANCE.
No possibility to retry any situation.
If we compare our performance the first time in a new situation, with the historical one...
And still we are not in life or death situation at our computer.
Some of the most brave officers had a mental breakdown during battle, and fell into hopeless panic before their instruments in real wartime...
Excelent points Hpasp and I completly agree with you!
For example the first time that I tried a LinebakerII scenario (one of the two B-52 bombings missions) I also wasn't able to shoot down anyone and I was destroyed very soon by an enemy ARM (Shrike if I'm not mistaken).
