Dan, 5J

s=ut +½ g t^2

Both land simultaneously at 0.56 +/- 0.01 secs.
Is that only true in a vacuum? Or from a short height. Heavier objects fall faster in the real world.
More important question if you had mounted firearms on a glider how much would the glide angle be reduced by recoil? And does the effect change at different speeds?
