Willie McKay employed Dave Henderson to arrange the flights for Sala...Dave Henderson is regarded as an aviation expert & known to be closely linked to both Willie McKay & the aircraft used.
Dave Henderson was fully aware that David Ibbotson was only a PRIVATE PILOT with DAYLIGHT FLIGHT RESTRICTIONS so any inference from Henderson that he wasn't aware that David Ibbotson wasn't a commercial pilot is pure bullshit.
Dave Henderson is almost certainly culpable in all of this & he will be getting dissected by all the aviation investigation teams in what was known & what wasn't.
Getting back to the initial misidentity of the pilot has underlying issues..... I will throw this into the mix :
Dave Henderson is a commercial rated pilot with a night rating & IFR rating and quite current on the PA46 Malibu.
David Ibbotson was a private rated pilot with no night rating & no IFR rating and no currency on the PA46 Malibu.
One explanation for the misidentity is: A Flightplan in the name of Henderson might have been filed to allow IFR & Night flying as his licences permit that ( Ibbotson might have had copies of Hendersons licences to hoodwink the system ? ).
Henderson knows the truth and it will need to come out in the Aviation investigation, I would guess there will be quite a lot of bullshit with a small piece of facts in what Henderson will disclose or portray the incident as.
The facts are known that David Ibbotson was colourblind & restricted to day flight only, the main people with Sala's & Ibbotson's deaths on their hands are Willie McKay & Dave Henderson and I am confident that they both knew that Ibbotson was colourblind & restricted to day flight only.
Ultimately Ibbotson signed his & Sala's deaths off by making that flight but I am guessing it was something he was pressured into by McKay and Henderson.
