Well that explains one part of your allegations - it was obviously sub judice until the report was out.
It doesn't explain any of your other allegations though, particularly the stuff about 90% of pax being unconscious during a flight. In fact, the report on the CAA website, regarding the incident to G-JEAK, says the following:
There has been no incident reported to the CAA, involving adverse effects to BAE 146 flight crew, due to oil contamination of ECS air, since June 2002.
... and that report was last updated in March 2004.
Kind of blows a lot of the allegations here out of the water really...
