Mig15
Ok I get what you mean, I though you meant pull them out and leave them.
Ok once a year and rotate the airframe then yes i think that would be good. it has happened at Cosford and I have a nice photo of the Lanc outside hangar 1 at Dux as well.
I wouldnt object if a total smoking ban was introduced at these places. It appears the NMM fire was the result of a stray fag but (or was that Fags Butt
)
