Why not an airlift for Burma?

This article was interesting and helped answer a question I had about it myself... why not just drop food in an airlift?

" Oxfam and other agencies have well-trained disaster specialists ready and waiting to go. The Burmese authorities must allow them in to do their job. However until that happens, calls for air drops must be resisted. They will make good television and fulfil the need to do something - anything - to help relieve the suffering in Burma.
But air drops are expensive, inefficient and not the best way to help desperate people on the ground. "

But the comments at the bottom of the link offer a lot of good contrarian reasons to do SOMETHING.
