Got any idea what was going on?

Aviation VHF radio communications are Amplitude Modulated, so it only
requires a simple diode/rectifier to detect them, unlike FM. Obviously
the iPod was acting as a wide-band or un-tuned radio frequency
receiver and detector, and combining the iTunes audio with the audio
from all the aircraft transmissions within line-of-sight at 9,500'.

Perhaps Apple will consider electrically shielding their products if
they become aware of this issue.
