- it is readily apparent that they had spoken to the airline fairly quickly or the CEO would not have issued his statement so soon before NTSB arrived..
I've heard no evidence from the NTSB that they've had information from the crew. Everything that Deborah Hersman said seemed to refer to what they've acquired from CVR / FDR.
When asked by the press who was flying the plane, she said that she didn't know, but intended to know by Monday. Since that seems a fairly obvious question to ask had the pilots been interviewed, and since the NTSB can presumably tell from the FDR which side of the cockpit was doing the business on the approach, I infer that a) she hadn't spoke to the pilots or b) the pilots had not disclosed who was sitting where.
Within a couple of hours of BA38, we knew exactly who'd been flying the plane.
