Well thats not exactly true, I'm sure many people have. I just earlier today managed to do it on realistic; but with limited fuel only. Its not possible to do it with limited ammo.
Basically go towards the first group and when the second group arrive tell your wingmen to attack mission critical targets, and whatever they do not go for you do. Usually two will break off to attack one pair while the other goes alone.
In regards to attacking, go straight for them at the same alt and fire, as soon as you go past go straight up and reduce throttle to 20%, wait for critical speed warning and then push the nose down, at this point you should be between 60-110 k/m above, gives you plenty of time to strafe both bombers before hitting their alt again. If you dont, sweep up again.
When firing only let off 2/3 rounds at a time, the amount of kick-back from the planes guns shake it to much, only firing this many gives it time to return to its original firing position. This way if you aim at their engines it will take only 1/2 bursts to bring one down.
Now, I'm having REAL trouble on 'The Babysitter' mission
