Cofty,
Did you watch the 2nd video?
Just because there is a lot of nonsense on the internet you will be committing a fallacy to assume that all sensational information on the internet is garbage.
Sometimes you have to look at the context.
Most of these guys had serious careers doing what they liked. They are retired and probably have decent government pensions.
They aren't looking for opportunities to be ridiculed. They aren't looking for adventure or celebrity. They certainly aren't in need of the excitement of airplane rides to conferences.
And they are the few that have decided it is worthwhile to step forward. Based on their description of events
there are a lot of people at all ranks that shared these situations with them.
