Okay, don't know the factuality, if that is a word, but get my drift, or the accuracy, but here is a post from another site, and unfamiliar with OnStar, well those that are may be able to shed light....
"When a vehicle equipped with Onstar receives a "hit" hard enough to deploy the airbags,the Onstar system in the vehicle automatically sends an emergency message to Onstar and the operators call to ask if the occupants are ok. That is the origination of the 911 call in the beach fatalities on Assateague. The vehicle was upside down according to the report. It is my belief that the antenna for Onstar is located in the roof of the vehicles. Upside down in salt water it is not very effective. The prohibited area on Assateague might be there because there is unexploded ordinance in that area. Those "mapping" programs aren't accurate once off the roads.FYI"
Like said, I don't know anything about this aspect, so chime in and straighten me out.
