pfffft specifications are like instruction manuals, no need to look at them 

Ok, I was tired when I posted the story, here is the spec's:Crew: 2–3 (pilot, radar operator, optional gunner)

Bombs: for ground attack, four bombs of up to 1,600 lb (726 kg) each or six 5 in (127 mm) HVAR unguided rockets could be carried under the wings. Some aircraft could also carry one 1,000 lb (454 kg) bomb under the fuselage.
One of the interesting aspects of this aircraft features was the "spoilers", which have proved, on certain types of wings, the most efficient way to create and maintain a turn. I would bet that when they designed the spoilers into the aircraft, most of the talk about spoilers were just theory, but after installation on production models, proved to be a asset to the aircraft.
