Why would they create a no fly zone around the disaster area.
I asked myself the same question, after reading posts on the New Orleans Tourist Forum on VirtualTourist.com from a guy with a flight services business in Lafayette who claimed that he has been trying to offer assistance and keeps getting blown off. I can't post the link because the thread just got pulled; this pilot is very frustrated and his posts tended to turn into stream-of-consciousness rants that were somewhat hard to decipher. I only wish I had cut-and-pasted the pertinent parts of them earlier.
VirtualTourist.com seems to be pro-Red Cross donations only, so I have a feeling that the response I posted with specific local addresses will be pulled momentarily. But as long as one person sees it and is prompted to act, then my mission is accomplished!
