Re: Re: ARES and Satellites



Here, Here!!!

Having been through the Murrah Building bombing, May 3rd, 1999 and May 8th,
2003, I can say with firm and full voice the cel system is the first to go
down/jam up/quit/etc.  After the Murrah Building bombing, it was a full two
weeks before cel service returned to normal in the downtown area.  After
both tornadoes, again it was several days before service came back.  Fact of
life: in the first critical hours/days of an emergency, DO NOT count on cel
service.
