While the driver and the command system got beaten up for the event, it is interesting to note that the spoiler response was being saturated quite early in the left turn that Holland entered. The speed and the bank resulted in exceeding the authority of the spoiler system, and the rudder, well, we have just commented on the rudder's authority. Occasionally, limits are there for very good reasons, bank limits on the Buff were rational, and needed to be respected.
Holland was a hotdog pilot who exceeded the limits and should justifiably be blamed for the crash. I well remember this event - this was not an aircraft issue, it was a driver issue. Watching video of that crash all I can think is how did the pilot imagine any lift would be generated at that bank angle; at his altitude there was no escape. This was not a crop duster; spoiler response did not cause this crash.
