It has been reported that crew in the following aircraft at holding point (tower frequency) heard the crew advise ATC of 'an airspeed issue' and 'controllability problems' whilst declaring their intention to turn back.
This is not something that appears to be reported at present, which seems odd. (media)
Where is the manufacturer in all this? Funny how the party line always refers to safety, however those in the industry know and understand all too well the commercial prerogative will normally (covertly) take precedence.
Condolences to those people who have been directly affected by this tragic event.
