When the chair of the U.S. National Transportation Safety Board appeared before
the House Transportation and Infrastructure Committee this week, he was asked
"Could you just tell us again in plain English why we don't know if this
operator was on the phone three weeks after the accident?" He had trouble
answering, because although the NTSB has detailed timestamped data for the
engineer's cell phone records, and they have physical access to the phone and
the phone's passwords, they can't figure out the data's time zones. The cell
phone companies don't know either.
