Remoak,
Well, as a BAe 146 pilot I stopped flying after 16 years on the aircraft as my memory was awful and I didn't feel safe any more.
A year later, when they tested my blood / fat, they found it full of OP's and a cocktail of other chemicals plus measurable cognitive dysfunction.
Don't you think it might be appropriate for 'first world' countries to check the blood / fat of deceased pilots for OP's?
The only doubt seems to be in vested interests parties - ask any victim who has been affected and they will tell you that they know - 100%.
Here is the contact for getting tested:
Dr John McLaren Howard
Acumen
PO Box 129
Tiverton
Devon
EX16 0AJ.
Tel: +44 (0)7707 877175.
If you rely on the State NHS test - they will tell you are OK, as your blood is -
red.
