host of "quest means business" richard quest and also the former chairman of the ntsb. you were monitoring the press conference. what jumped out at you about what officials were saying? >> really, the comments that it was not technical and it was not human error but external forces or external reasons, i just don't see at this point that they can make such a claim. it's an extraordinary claim to make but it is not surprising that the airline would be saying that at this particular point. the reality is, until there's been a forensic examination of the wreckage to see if any explosive residue, at least a full data readout of the black boxes, we simply don't know. all we know is that at a particular point plane basically fell out the air and lost all of its air speed. the reasons why are simply not known.
