All the hangars I've ever been in have been cold, draughty and full of echoes. I would have thought that almost anywhere else would have been preferable to a hangar for holding a meeting.
Dunno, Goodwood's Alpine apres ski Hangar 2 was rather nice during the revival weekend. Probably back to cold and draughty now though - they might even let SlipSlider put his aeroplane back in it...
