The HI-Vis thing Will have no efect in the day time and will only lul you into a false sence of security.
I speak as one who had NO hi-vis for 10 years on the ramp at LHR night and day for 10 years without incident. Then the first day that the H & S gods make me put one of these miracle anti accident vests on I come very close to getting run down as JSY at 0600 on a sunday (day light).
I think that after dark and in poor vis these things have there place but dont fool your self that on a nice day the hi-vis is worth the effort of putting it on.
I like the greek islands.......... real flying and no one gives a flying f**k about the H&S bull !!.
