writes "Some scientists believe that there is a larger, more sinister type of ice-chunk precipitation besides hail which can form outside of storms, making even the largest hailstones look puny in comparison. There is a great deal of disagreement in the scientific community regarding the origin of these falling slabs of ice, but it is certain that something is causing massive frozen chunks (weighing between 6 pounds to as much as 400 pounds) to occasionally drop from seemingly clear blue skies. The objects are called megacryometeors.
If these things are forming on, and then becoming dislodged from large aircraft, you would think there is the potential for a massive lawsuit should one of these ice chunks actually kill someone. Is the FAA and the airline industry really covering up the source of these ice chunks (AKA; megacryometeors)?"Link to Original Source
