[Star Wars 1977] Why did the pilots have to take turns at attacks on the Death Star's flaw? If they staggered, a squad could have ended up behind Vader or at least given Vader more, spread-out targets to hit.

I mean, Luke's squad was waiting around while other trios did their run. Why not make it a big attack of 6-9 ships instead of 3?

If they'd staggered, they would have been lining up one-by-one for the Death Star's autocannons. Remember that only Vader and his wingmen were in fighters. Tarkin was relying on the Death Star's point defense system. 

Given that the thing basically had a big glowing weak point, the Rebellion's plan was basically to group up and make a break for it. The unspoken element of the plan is "Hey, they can't shoot down *all* of us.... right?"
