Hopefully that idea is dead and buried !!!! Shame so much time, effort and money was wasted on the idea.

Time is right for the “Milestones” building to be rebranded, indeed no branding is required it simply needs connecting properly to the main building and the original main entrance reusing. A good idea would be better information / direction to the other buildings, BoB hangar and Graham White hangar always have seemed remote. Could the space between Milestones and GW be used as some kind of external / covered display. Thinking a WW1 canvas hanger, WW2 revetment, a cold war HAS with appropriate ground equipment ?

Not sure how suitable the old workshop buildings would be for the new cafe ? If space can be found on the site a better solution would be a new build cafe with assocatied play area, ect. I do not know the local Hendon area so have no idea if this would work but if the cafe were run by at external contractor could it be open outside of museum opening times ? Could it become a destination / meeting point in its own right ? Maybe sounds a bit kitsch but there are many examples of such theme restaurants in the USA.
