Probably as much harm as answering questions like 'where do airline crews stay on layovers in London' which pops up occasionally. I remember one crew attacked in London outside the hotel. It seems innocuous, but does anybody know who is LGW15 and why he wants to know and are they quite sure he is not looking for targets? We are all supposed to be observant and security conscious. I'm sure it is in all innocence, but looking at the replies, there appears to be mild suspicion from somebody else too.
