Whether or not certain equipment was or was not subsequently delivered is irrelevant. The only important point connected to your pet theory is that the equipment you describe
was not fitted to ZD576 at the time of the accident and cannot have been even a contributory factor. For, I hope, total clarification, what I meant by "or any other Chinook Mk2" is that no Chinook Mk2 was fitted with such equipment at the time of the accident. Finding out, even "just for interest, say" is a waste of time - something fitted to the aircraft (if it was)
after the accident is as relevant as saying that it was snowing in Luxembourg the morning after the accident.
