This PIP discussion just reminded me of some experiments, years ago:
The task was to place a microphone at a falcons nest about 30 meters
up on a cliff.
Was it possible to mount a microphone at a balloon? With cable? We
could not get a big enough balloon.
Was it possible to mount a microphone at an arrow and use a strong bow?
We tested it, and with a very tiny cable it was possible to shot it
about 50 meters straight up. And we had no hum or other noise,
although the cable was nearly 70 meters.
At another occasion we had 2 PIP mic's mounted into a cork loon and
then pieces of plastic foam around the > 120 meter cable, to keep it
floating. Parabol recordings of the loons was impossible, cause of
the noise from the water.
