So where was the debris trail? I watched the balloon as it was shot down. The balloon popped and the payload went straight down. The same thing could have been done in MT and the recovery would have been easier.
Biden shot it over the water so there COULD NOT be any data or equipment or camera or radio/telemetry recovery.
If you look closely at the video, you can see the payload free fall. In about 7 or 8seconds you can see a series of small flashes trailing the payload. I believe these may have been explosives detonating in or on the sensor packages, destroying them. They could have been triggered remotely or by an altimeter which triggered self destruct mechanisms once a certain descent velocity was attained.
