What is it about Bristow and Cancer, or is it just because we are all getting older. I have a theory that spending half our working lives sucking in exhaust fumes has not helped.
I remember balancing a 412 tail rotor once, the next day I had to take the morning off with severe gas ingestion. I had not realized that the downwash from the 412 is not the same as the 212, and working around the back does not do you any good.
On a personal note, I had a fight with non Hodgkins Lymphoma, but am OK now.
