Royal Flight pilots never hit light fittings, so what good for the head of the Betty Windsor Flying Club should be good enough for you.
But just to 'hammer' home the point - inset runway light fittings have been designed to build standards. Both the UK and US publish these. Except following the famous failure of a fitting at LHR studies have shown that shear forces imparted from a/c wheels and tyres are much higher than in the old days.
Steps have been taken to reduce the risk and since then no more incidents have been reported.
So do your part and reduce wear and tear on the fittings eh?
