This still seems odd
Taking drugs \ drinking and flying is only ever going to end with one result. Flying after class A drugs is suicide. I find it very hard to believe he knowingly dropped an E and then got into an aircraft with a passenger. Either he was spiked, or he took the tablet thinking it was something else. If he did knowingly take ecstacy and then got into an aircraft he commited suicide. The only other thing I wonder was if the MDMA was in the passenger's body and samples got contaminated ? We'll never know what truly happened that fateful day.
