I just remembered another song that although I don't think that it specifically mentions flying, had to do with a bad flying incident.
That song is "American Pie" which mentions "The Day The Music Died" which the songwriter said has to do with the deaths (in a plane crash) of Buddy Holly, Ritchie Valens and The Big Bopper.
Thanks very much! While I did know many of them - I did find some real gems among your suggestions. They will be featured in upcoming podcasts and at Arlington Radio - which this year will stream live on the internet 24 hours a day for the entire week.
