I did think Deborah handled the presentation well, but I agree with it being a little 'premature' since it is based only on statements and 'observations' before both CVR and FDR have been analysed (unless, of course, a 'sneak' view has been had). We must treat the 'information' released as preliminary and not jump to conclusions.
Out of interest, are the IAS's being quoted from observed data (ADSB or radar) or crew statements?
