So you're saying that the sat is wrong? Red zone is a red zone, no matter what the source of the data.
The red zone show in a sat map is the temperature .. no more
That's not what see the radar of the aircraft ..
MTO satellite, shows in red the coldest temperatures of the cloud tops, while the MTO airborne radar indicates the density of the ice or congestive clouds. It is more dense and the cloud is active, the more dangerous it is and of course it will be shown in red on the radar screen meaning the green opposite the only water detection.
As far as I'm aware the point of an accident investigation is to find out what happened, not to show the general public what the flight crew would see
So what the point to show what the flight crew can not seen ??
