<<The sound is terrible. I'll try to get it improved, but Mum also makes a few comments about the sound track ....
"Bert Foley ~ is the voice of Airfield Control, I bet you hadn't realised that I [Mary Waddington] am the voice of Ground Control. The bell at the start is the large Camel Bell ! and the aircraft sound was my hairdryer and the whole thing ~ splicing, sound etc done in our lounge after you and Simon had gone to bed!!!!">>
I'm a TV post production sound mixer so obviously find it fascinating!
Funny that he should be 'Bert Foley' as the originator of the 'art' of adding sounds to silent movies was an American 'Jack Foley'. Thus there is a breed of person working in the film industry called 'Foley Artists'. There job is to recreate all the sounds that were either unusable or were covered with dialogue, usually to enable foreign language versions to made. Also of course to heighten the action etc in a movie...just like your mother was doing!
