Anyone here ever found a radiosonde, by any chance?

How would you find one with anything but?

One fell onto a school building in E. London and the other onto
a school playing field *in north-west Essex. Both had small brown labels to
say that that there was no need (or reward) to return them.

So a miniature radio, altimeter and temperature gauge are worthless?
