Procedure
We were ILS to both 4's; departing 4L. Local 2 departed a B757; which was off the departure end of 4R by the time Aircraft X was short final and began his missed approach. I was not confident in the performance of the Widebody to make a tight enough turn and thought that the planes would end up closer together; so I kept him on runway heading and as soon as I saw Aircraft Y was through 2;000 cleared him to that altitude. We had over 30 degrees divergence; 850 FT and increasing of altitude separation but the super had to fly through the flight path of the B757.This set up is difficult due to the flight path of the 4L departure crossing 4R departure end.
I was working Departure Local Control on the 4s and cleared Aircraft Y for takeoff while the Aircraft X; [a Widebody] was on a 3.5 mile final for Runway 4R. As Aircraft Y climbed out of 1;500 it turned right to a heading of 100; while in the turn Aircraft X went on a miss because of an unstable approach. Local Control 1 tried to stop the Aircraft X at 1;500 but the pilot could not comply. I then expedited Aircraft Y to climb; Aircraft Y was on a 100 heading and Aircraft X was on a 40 heading; but at a point it appeared the altitude was lost (850) and the Widebody flew through the flight path of the Aircraft Y. The 4s are a difficult setup at JFK because the departure has to cross the fight path of the possible miss approach.
Reporters state an aircraft went around due to unstable approach and flew into wake turbulence of another aircraft and which was also a distance of less than standard separation.
