Slightly off topic but... I got a very lucky "neversaw'em" kill one day while trying to track down someone who upped a jeep and parked it in deep tree cover to keep the base flashing. I was in an A-20, there was a FI up and a couple fighters too. We were criss-crossing the GV dar square trying to find him... no dice. After four passes I got bored and decided to land and find something else to do. I pull up and bank steeply to the left, 70° or so, and while in the turn I pickle off all four of the wing mounted bombs thinking it will make for easier plane handling at low speed on approach.
As I start to level out headed for the field, I get a kill message in the text buffer, followed by 4 distant BOOMS. I thought he must have towered and I got a proxy but soon I got a PM from one very angry jeeper. "You cheatin' hacking *&^%*&, you never flew close enough to spot me .... etc." I replied that I never did see him, I was just dumping bombs and going back to base and must have gotten an accidental hit. He wasn't buying it one bit. Told me he watched the bomb coming in like it was laser guided, how it hit a foot in front of his jeep, etc. so I must have knew where he was. Nope, was just a pure lucky hit.
As to the original topic question, the TA is your best friend comes to dive bombing. Learn the angle that works best for what you like to fly and learn to fly an approach that works for you. Use that cross pipper in the TA until you have a working idea of where your bomb will go for a given approach. I find that if I stick close to the parameters (speed, dive angle) I trained with, I can hit targets with decent success. If I miss, it's almost always because I veered too far from those familiar parameters.
