[*]Fun fact I didn't know - RIAT are not allowed to mow the grass on the airfield. It's kept at a particular length (it's quite long IIRC) as a deterrent to birds.
The grass length is mentioned on the RIAT website, quoted as being "At least 7 inches"
[*]Re. the 10m exclusion zone for tents/windbreaks/ladders etc - a question was asked on whether they could be more stringently enforced, and an idea proposed to re-introduce a white line to delineate the 10m exclusion zone. DBH have taken it aboard to see whether it can be done. Andy recognised that it used to be done, and might just be something that was forgotten. In principle, and the reaction from those at DBH, it seemed like an easy enough idea to implement.
Possible solution, put the tannoy speakers on the 10m line as a more visible deliniation marker ?
