Every time I vulch Hawking AFB killing enemy planes on the ground, taking off or prior to their take off.
I don't have the numbers but I estimate that 20% + of my kills are the direct result of vulching... It is always a blast to see all that Flak/AAA firing among with some dogfights around. Usually take off with a bomb (unless I'm using the E1), after destroying ships or ground units I'll go there to empty my guns BnZing, then I'll run home towards the French coast like a girlie dragging Spits and Hurries to be gangbanged by the rest of the LW heading England... Sometimes I'm the one that is gangbanged.
Regards.
PS: Today was looking for trains for about 30 minutes, then a single Hurri jumped me, I then dove to run (as usual) and as soon I reached ground level I couldn't believe what I've had in front of me... The damn train locomotive expelling tons of withe smoke, used a little rudder and Boom!!! I could see the flames surrounding my airplane as it passed by... I was lucky not being caught in the blast.
