I would imagine that Dave Henderson isn't commenting because he realises that he has monumentally ****ed up by asking / letting David Ibbotson do the flight.
The McKay's are scrambling around like 'Rats on a sinking ship'
Henderson was a good friend of Ibbotson so I would imagine that Henderson feels very bad that his friend died in a flight he had organised ( I use the words 'Good Friend' loosely though as I wouldn't send a friend who isn't legal to do a flight at night on such a flight )
This part of the link is Willie McKay trying to clear his own name whilst doing his utmost to " Throw Henderson under the bus "
For it to be classed as cost-sharing, pilot David Ibbotson would have had to have been making the journey regardless, dictating to Sala when the plane was leaving and sharing the cost of the flight equally with him.
Agent Willie McKay, who commissioned the flight for Sala, said the flight from Nantes to Cardiff was not a cost-sharing arrangement.
He said "Emi wasn't paying anything" and that he was going to pay "whatever Dave [Henderson] was going to charge".
Mr McKay said David Henderson was the pilot he used most frequently to arrange his flights.
It is thought Mr Henderson was not available for the Sala flight, so he asked Mr Ibbotson to do the job.
Payment would usually be made after a flight due to the varying amounts paid for landing fees at different airports.
The article has some interesting snippets.
(1) Willie McKay made the timing arrangements so I doubt David Ibbotson had any control over the departure time( I still believe that David Ibbotson thought he was flying back in daylight hours which is why he filed a ICAO Flightplan @ 0900hrs (ish)
I suspect either McKay or Henderson sprang the night departure on Ibbotson after his initial flightplan was filed.
(2) Willie McKay stating that it wasn't a costsharing flight is throwing a now deceased man under the bus & shoving Henderson under the same bus. ( The throwing the now deceased pilot under the bus now potentially puts the Ibbotson family in a more vulnerable position than they were )
(3)Willie McKay stating that payment would usually be made after a flight due to the varying amounts paid for landing fees at different airports is another 'loophole' that McKay thinks removes that it wasn't a flight that Ibbotson was already paid for. That 'loophole' won't work for him as a defence because either him or Henderson had agreed a rate with Ibbotson. Willie McKay had previously said that he had paid Dave Henderson to do the job so McKay had paid monies for this trip.
I think Willie McKay knows he is ****ed now & is just clambering away to take as many others down with him when the 'shit really hits the fan'
