Right on. Nearly all accidents/incidents are caused by multiple factors. But huge, and it seems mostly overshadowed, was the crew’s intentionally turning off ADS-B, and pilot Rebecca Lobach’s failure to follow direction from instructor‘s warning to change courseYes, and this is why the NTSB brushes past the helicopter crew’s fatal error and tries to put the majority of the blame on the special helicopter route. The present day pilot’s lack of skill and experience is concerning and in this case caused a crew of 2 to allow their aircraft to hit another aircraft that they saw and we trying to miss. The FAA would have to create and enforce a “fix” for this and FAA management does not have the energy or the intelligence to create and implement training and procedures for a can of worms like this.
