CASA before the accident were definately 'after him' in the sense that several ex students and staff were approached and basically demanded to give statements about incidents and events that had happened over past years. Saying 'no' was not an acceptable response.
They appeared to be building their case so it definately stuck, CASA in the past had been made to look foolish by Barry because of their lack of doing things the 'right way'. Barry had a history of going through CFIs/CPs that stood up to him, and only ended up with those that didn't say no to him, he was MD but was effectively CFI/CP as he did what he wanted, he just wasn't able to be both of those positions due to his problems with CASA. He was a VERY strong character, and the sort of person that if you told him something he didn't want to hear, would have in no uncertain terms told you where to go.
Likeable enough character, and a bold pilot, but you know what they say about them. All things aside the sad thing in this case was the innocent, fare paying pax and his partner who thought she was doing a nice thing for obviously something special to them.
Aviation has its risks, especially in a 'limited' aircraft like the Yak, but the fact remains that he did not legally meet the medical requirements to be flying the flight, as a pilot it is your DUTY to ensure that you are legal to conduct the flight each time you put the belt on. All of those that were aware this was going on, without standing up and doing something about it, when clearly Barry wouldn't, have some element of blood on their hands, and at the time it was well known at AF that it was going on. Amazing how many people have a bad memory at times like this...
