Exactly, Pull What. I asked the gal in the tower at Wellesborne, while waiting for my aircraft to be flight tested...it was a murky afternoon. And it was very difficult for her to see and keep track of the traffic, practically nobody bothered to put their lights on. Why not, I wonder, couldn't be bothered? or worried about running down the batteries??? or just never thought it could be a difficulty for anybody else. I wonder if since five years ago or thereabouts, if the situation has improved?
