They didn't fly directly into the storm they deviated west instead of east as did half the flights. They took a 12 degree left deviation to avoid weather. Apparently their pitot tubes froze up because of faulty probes that hadn't been replaced yet. When they froze up they pulled back into a deep stall for some unknown reason and crashed. No data of severe weather, just choppy conditions typical of that area. I hope the final report comes out soon so the nonsense can go away. Pilots all pick their way through weather depending on what is happening at the moment, not what another flight did 30 minutes before them. Weather changes rapidly sometimes.
