Having suffered from this myself, some years back,and still have the odd migraines,2 people,Susan Michaelis( a Medic) and Tristan Loraine(Ex BA) formed an Aerotoxic Association with John Hoyte in the chair,with whom I used to fly!They started the ball rolling a full decade ago with little or no results as the Officialdom stated the Historical Data Base was not sufficient to enable the" Authority"to make a prognosis of any long term health problems!!That is exactly what the Lords and Masters of said Authority said to my Wife down at the Beehive Gatwick,when they removed my licence medical-Luckily just before I was due to retire.Meanwhile a LOT of my old mates have succumbed to a number of cancer related or brain related terminal health problems.
Maybe,at last, something may happem.
