Well we all know that it will always be pilot error, but I wouldnt go on the flightaware picture alone. I have been using flightaware for years, and to be honest, the flight could have been going for hours, yet obviously the radar snapshot overlaid has to have been a single loop on the radar, the question is when? Especially when these cells can move at a very good pace, and we as pilots are trying to guestimate an aproximate 20 mile bearth. This is not an exact science for sure.
