I am a PPL/airline pax, so please treat this comment as an uninformed question, from someone with no relevant aviation knowledge, being upfront about that.
If the groundspeed at ORARO is true, due you think there is any possibility could have been tornadic activity?
I remember well the F28 that encountered a tornado in the Netherlands and broke up middair.
Please don't be irriated if the met info or other reasons make this unlikley/impossible, my only interest in this is as a frequent passenger on this a/c type and whether this accident was a 'one off.' I am not passing an opinion, just asking a question.
Perhaps we will never know.
