Neglecting air resistance, it will take the capsule about
  t = √(2d/g) = √(2*500/9.8) ≈ 10.1 seconds to fall to the ground.
Thus, it will hit the ground about (55 m/s)*(10.1 s) = 555.5 m ahead of where it is dropped.
That point will be ArcTan(500/555.5) ≈ 42° below the horizontal line of sight of the pilot.
