Evening, I'm hoping for a bit of advice... I'm wondering if any ex/or currently serving WAFU's are aware of known carcinogenic substances linked to the Lynx or Seaking aircrafts. I lost my father recently to a form of Lymphoma aged 56. He retired as an PO(AEM). Working mainly on Lynx and Sea Kings (various Mks). His service ran from 1976-1998. I'm interested mainly in the Lynx as a large amount of his ex navy AEM mates have contracted the same illness. I also work with ex-Army Air Core maintainers who worked on the Army variant Lynx, a number of these have also contracted lymphoma. A rare coincidence maybe? I'm not interested in the "blame" culture or after a legal battle. Far from it, just if anyone is aware of this coincidence or any answer as to why this might be happening? Thank you for your time.
