How far did Tom Petty free fall?

This evening, Laura and I listened to Tom Petty's "Free Falling" and became curious about just how far he free falls during the song.

First, a little research:
And now comes the math:
  • Tom Petty is in free fall for 4 minutes + 15 seconds - (1 minutes + 9 seconds) = 3 minutes + 6 seconds.
  • He takes 55 m/s / 9.8 m/s^2 = 5.6 seconds to reach terminal velocity.
  • He travels (9.8 m/s^2 * (5.6 s)^2) / 2 = 154 meters before reaching terminal velocity.
  • Assuming that he stops free falling at the end of the song, he free falls for a total of 3 minutes + 0.4 seconds * 55 m/s + 154 m = 10 kilometers.
We can only conclude that he jumped from a passenger jet at a cruising altitude of about 33,000 feet. Ouch.
