I am the one that got the audio and there is more that I am working on recovering.
Many thanks for sharing these audio files. Some questions if I may:
* Are these audio files sourced (as reported on other forums) from the lady who now lives in Washington state and in 1971, worked for Northwest in Detroit?
* Is there any way to establish the authenticity of these recordings?
* Are the audio files arranged as follows:
00m00s to 04m33s: Sea-Tac ground control frequency (121.7 mhz)
04m33s to 07m12s: Northwest company frequency (131.9 mhz)
07m12s to 09m26s: Sea-Tac ground control frequency (121.7 mhz)
09m26s to 12m05s: Northwest company frequency (131.9 mhz)
* How are the speakers identified? For example, how does one distinguish the Captain from the First Officer?
* How would the crew be able to talk to Soderlind in real time, when the crew were at Sea-Tac and Soderlind was in Minneapolis (far out of radio range), and there were no cell-phones?
