Heathrow before the Europa terminal and Queens building
I've been looking to get a sense of how Heathrow worked before the permanent structures (Europa and Queens buildings) were completed post-war. I've seen discussions on here about it's past, with pictures of the post war tents for example, and it's been very interesting. But I've gained little grasp on how it was organised and how it was experienced by passengers. Is there a good source I could turn to? Perhaps you have any experiences of visiting Heathrow before the proper terminals were built?
Thank you in advance
