The downsides to just air dropping supplies into Burma are:
1. Who, on the receiving side, is going to be able to open the containers and arrange for whatever's inside to be distributed to who needs it.
2. Airdrops are the only way to insert the supplies into Burma, because the government is in control of all available air strips. The one highly successful use of an airlift to counter a ground blockade was during the Berlin Blockade, but the planes had an Allied-controlled airport to land and offload supplies in an orderly fashion.
3. Airdrops are an extremely inefficient way of delivering anything. What you need is a good port facility or air strips and the capacity on site to unload and store the stuff.
4. Then, there's the question about whether the Burmese generals would be willing to start shooting planes out of the sky. I think the answer to that is probably yes. Also, read the link to the Berlin Blockade. It didn't transpire without loss of British and American lives due to Soviet actions.
5. In addition to watching a million or so people die, we'd probably end up watching tons of goods rot unopened and unused.
6. Given the craven nature of the regime, about the only thing that would happen to most of it, is that it would be rounded up by the military and impounded.
Illegitimi non carborundum.
