It always could be useful to involve other...while the pilots are well involved in the certification process. All those systems, including the interiors and [Technical difficulty—Editor] are being certified as well. I find one of the big lacks is in the engineering systems. The systems engineering aspect has been what has caused those two crashes, because they did not do the safety analysis properly, which led them to assess a criticality level of failures that was not sufficiently high. If that had been done, more testing would have taken place.
