Four pounds of hardware ingested by a jet engine is going to do a shitload of damage.

Exactly. Given that most birds weigh less than 4 pounds and bird strikes can take an engine out completely.

Plus, if @jacquesm says it, it must be true. ;-)

These pico balloons weigh grams.

  • Yeah, I think ours was less than 10 grams.

    As rules go, IIRC at least here in the Czech Republic anything below 100 g is unregulated, you just need to have a licensed amateur radio operator, so that the probe can broadcast in the 20 meter WSPR band under his callsign.
