there seems to be some confusion over the term 'basket' here.
The two-person basket, raised and lowered on a winch looks like this:
The mass rescue, 16 person basket carried on the cargo hook (with a secondary safety) looks like this:
The large 16 man basket is relatively heavy and stable, and it's only suitable for short range rescues - inshore, within an oilfield or where rescue ships are nearby.
Obviously, some supervision of loading is needed to prevent overloading. It's unlikely that people will fall out as has been suggested. One advantage is that it will transport injured, unconcious and children. it is unlikely to be the liability that it is being described on here. The US Air National Guard are equipping with it, so it can't be that awful.
Think outside the box - but inside the basket.
