Chretien made the right decision but for the wrong reason!
The original EH-101 contract had (in my opinion) 'PROBLEM' written all over it in capital, bold, italic red ink.
The Air Force was going to accept the helicopters in Yeovil, fly them to Bristol, have them shipped across the Atlantic to Halifax harbor, fly them to Halifax International, hand them over to the prime contractor, who would them hand them over to the avionics installer, who would then install the government furnished avionics, and then hand them back to the prime contractor who would hand them back to the Air Force for acceptance. So if anything didn't work, the amount of finger pointing as to who was to blame would have taken a 10 armed Hindu deity.
But the 101 was the best machine for the mission as then defined.
