Given that there's little flying to do at the moment, I got my aviation life-jacket out and noticed it was 14 months past the time I should have had it serviced.
Out of interest I pulled the toggle, guess what, it didn't open !!

(turned out the cannister had got loose)
Anecdotally I've chatted to a few pilots, who like me, were more casual with lifejacket servicing than we should be. If the big shiny thing goes AWOL over water, our lifejacket will become our best friend ! Another lesson learnt and my LifeJacket will be well looked after from now !
