"About WSI InFlight
The WSI InFlight system continuously broadcasts near real-time WSI aviation
weather information directly to the cockpit using a geo-synchronous
satellite service. Information includes current observed and forecast
conditions, as well as WSI NOWrad®, a high quality mosaic of the NEXRAD
Doppler radar system. WSI InFlight has complete, uninterrupted continental
United States signal reception at any altitude. The system features a
sophisticated 'high glance' value user interface that is easy to interpret
and thereby increases situational awareness. WSI aviation weather data is
provided on an 'always on' basis for a low cost, flat-fee subscription."

Saw a revealing presentation at a NATCA controller's conference. They
showed
a slide with several large cells being displayed, and indicated the
position
of a 172 when the scenario began. The pilot told the controller that if
he
could have a certain heading, he would be clear of the cell he saw on his
screen and could proceed to his destination. Unfortunately, by the time
he
got to the geographical area which was nice and clear on his cockpit
display
at the time he asked for the heading, the cell had moved directly into
his
path with predictable results.

Do you have an NTSB report or an approximate date of this accident? As a
pilot of an aircraft equipped with in-cockpit WSI weather, I am
interesting
in reading more of the details surround it.
