"Experts say that airdrops, another measure Israel announced, are insufficient for the immense need in Gaza and dangerous to people on the ground."[1]
"[T]he airdrops have an advantage over trucks because planes can move aid to a particular location very quickly. But in terms of volume, the airdrops will be 'a supplement to, not a replacement for moving things in by ground.'"[2]
The airdrops killed people when 1) the containers landed on occupied tents and, 2) containers landed in the water and people drowned attempting to retrieve the aid. Trucks can also delivery vastly larger quantities of aid substantially faster and cheaper than planes.
