Sorry Karmen, they would have to pee out the window of the plane to hit the ground. The waste is collected and pumped out when on the ground after landing.
Up in SMith there is a helo base right near my wife's grandpa's place. He has had clumps of dirt , a crescent wrench and a 2 pound sledge hit his roof or front porch off the skids of the helos or out of the sling loads they carry to the firebases. When they carry a sling load they are not supposed to overfly residences, but it costs money to fly around them.
Ice is still better than the odd frozen crushed body that rains down from some idiot hiding in the landing gear bays on take off. When the plane lowers its gear to prepare for landing...bombs away.
