Balloons from 25 schools were launched in batches of five from RAF Cosford.
Each balloon carried a payload incorporatingÂ*twoÂ*small cameras and the
Raspberry Pi In The Sky telemetry tracker. The balloons transmitted on
unique frequencies ranging from 434.040 to 434.790 MHz.

Jason Bradburys balloon reached an altitude of 33 km before it burst and
the payload parachuted back to Earth. The next problem was finding it. He
tweeted:

Call out to my radio amateur friends. Need help finding 434.04mhz telemetry
binary code

The balloon was eventually found stuck up a tall tree.

The event was featured on the BBC TV show Midlands Today.
