Minotaur,
Ask Hollywd about a time (been awhile, few versions before rotating countries I think) about how he stopped a sneak attack on field 1 that I and another pilot were executing. Hollywd said he was in the hanger deciding what bird to fly when he saw the gooney bird come in and start dropping, so he popped the fly button and, as you can imagine, started strafing troops. I was flying a B17 and hadna gotten low enough to cap the field yet (and the 26 hadna been introduced yet). Simply put he laid waste to about 45minutes of flying time for us, but that's war sometimes =)
Frankly I dinnae understand why you're making such an issue out of this. It's very easy to stop and dinnae require you to spend the majority of your playing time in an endless, boring orbit around the field. When you land or get shot down look at the map for a minute instead of immediately popping the fly button. Take a look at "the big picture." If you see something fishy on dar go investigate it or put out a call on the country channel (or both =).
Raids are easy to identify by the lack or pinpoint dots or by the lone pinpoint dot that is headed directly towards a base and is up to 18miles out. That'll be the bomber climbing to altitude. There've been many times I've watched a marker progress across sectors suspecting it was a sneak attack. I'd guesstimate thier target by looking at thier track and what was strategically valuable (those who go to this effort are usually looking at starting a strategic campain), then position myself to intercept the goon as they get close. Sometimes I can fly 2 sorties while waiting to go intercept them. Sometimes I have to go as soon as I realize what's happening. But 1 person can prevent this. If you're bombing put out calls on the country channel. More than 1 call, because in the heat of a dogfight not many people are focused on the radio buffer and miss msgs. I know I have to hit the tab key and catch up after I've been turning with someone.
And if the bishcuits dinnae want to bother with stopping the attack, change to the rooks and join The Wrecking Crew =)
