Air Strikes

[RERomine]

How "safe" are air strikes in WinSPWW2?

In the various versions of SP out there, I find I suffer from "friendly fire" too often. So much so, I don't usually bother with air strikes in WinSPWW2. The only aircraft I generally use are spotters and transports because they don't shoot at my own units. In one battle I did use Stukas, but I made sure their approach to the target didn't pass near any of my units. Basically, I bombed some infantry units running down the bottom of the map into my rear area. I'm not sure what the infantry was up to. There was nothing back there to attack. By doing that, I effectively wasted my Stukas attacking enemy units that weren't a threat, just to keep my planes away from my own units.

How often do "friendly fire" air strikes typically occur?
