One of the local Detroit stations, WDIV, had extensive coverage of
this story as it was unfolding.

They covered the story without sensationalism or much speculation,
with telephone interviews of the US Coast Guard chapter at Grosse
Isle, and the Ontario Provincial Police.

Meterologist Paul Gross had a surprisingly ACCURATE description of
icing hazards in a low dewpoint spread (which was 0 at the time), and
supercooled droplets freezing and changing the shape of the airfoil.
The weather was okay for VFR flight earlier in the day, but was
degrading. Icing was the most popular speculation for the cause of
the crash shortly after it occurred.
