ET is no longer the chairman of the environmental standards committee. His important work exposing the hazards of contaminated bleed air may not have gone over well with some folks that may be too cozy with the aircraft manufacturers.
Neurotoxins aerosolized from over heated lubricants escaping engine seals which then contaminate cabin air is a major problem that could lead to class action lawsuits with multi million/billion dollar implications.
I urge all pilots to take fume events seriously and follow this issue closely.
