The CG Falcons are modified with a drop hatch, large search windows, an aux fuel tank and some other stuff. They carry two rafts, a de-watering pump and a utility can that can be dropped. There is a rail in the overhead to lower the drop into the hatch and it is connected to a 430' trail line with a big chute at one end and a small chute at the other. Hopefully you drape the trail line over the target and they haul the package in. If you miss then they might be out of luck. Winds are the trickiest part of the drop, so you try to fly straight into the wind. The drop is done from 200 feet at about 130 knots or so, with the flaps at 10. They do some freefall drops (usually data marker bouys) from 100 feet as well.
