C-130 Hercules is a very reliable plane. Don't worry

The C-130 does not have the capacity to transport this many people in one flight, especially including the gear they will most likely be taking with them. There may be several C-130s involved in this operation. It's possible that one C-130 could get all these NRDF personnel there in one day with several flights. I would expect that the C-130(s) will be involved in flight operations over the next several days (or weeks) in support of this operation.

I think that a billion person country has more than 450 disaster relief trained people.

On the other hand - there may be capacity to receive one plane, but not 10 - you don't know how long the infrastructure will be working.

My mind is with the people of Nepal, hoping for the best.
