Last in this series of airdrop pics (more later). This is the ultimate nightmare for the DZ party. Parachutes snagged in trees. At first glance looks like the Nav has miscalculated the CARP (Computed Air Release Point) calculation. But all may not be as it seems. All large airdrop loads had a mechanical disconnect on the riser line between the load and the parachute. Once the load was safely on the DZ the parachute could then drift off in the breeze without dragging the load with it. Or in the case of the heavy drop without turning the platform over.
As Brian the Nav and his colleagues would not have made such a mistake this is obviously what has happened here !
