Watched this great program last night on BBC4 all about flying in the 20's and 30's. It was really interesting to see how it was done in those early days with the first commercial passengers on Imperial Airways Silver service.
If you get a chance to see it and you are interested in the early days of flight I'm sure you will find it fascinating. Don't know if you can get it outside of Europe, maybe on BBC America or BBC world at some point.
Remember that chap who was so peed off with Qantas because there was no soap in the washroom. he may be interested to know that the toilet used to be a bucket with a curtain round it.
