There's an Australian song called "From Oakland to Brisbane" about Sir Charles Kingsford Smith, and his three crew members - Charles Ulm, Jim Warner and Harry Lyon when they made their Pacific crossing in 1928in the little plane, "Southern Cross. Don't know if you are interested in this as it isn't a song from the period but rather, of the period. Interestingly though, it was written after reading Kingsford-Smith's book about the flight and was sung by Jim (the writer of the song) to Kingsford-smith's son when he at re-enacted the flight back in the seventies. The Net is a great medium. Not only did Jim get to sing the song to a very hppy son of the great aviator, he also had an email from Jim Warner's son who wanted a recording of the song because he had seen it on Jim's website. What a thrill! Lyrics and sound here I hope I got the clicky thing right!
