So reports say five people have applied for asylum but has anyone been charged so far?
I am somewhat askance as to what some posters have said about their actions if they discovered a note in flight. Surely all threats should be taken seriously. That does not necessarily mean that it would constitute a red alert requiring the aircraft to land but surely such a note should be reported to the relevant authorities and kept as evidence.
Often terrorist groups will do a trial run to see whether any action is taken so they can use a later opportunity in similar circumstances.
