Catching fish from a balloon

[scottish_and_mental]

I've noticed you never stated the fish had to be HOOK caught so why not attach something like a lightweight lobster pot to the end or eel trap like device ( just thinking of your humping the fish up 3 km dilemma ) plus why not use a trip flare instead of a marker balloon ?

well as i said, and back to the auto gas filled balloon. trigger could release all sorts of armourment but the ballon to bring it up is a must. simple fish takes bait. the tug on the line activates balloon. balloon fills with whatever gas that is lighter than atmospheric. you would not need to play the poor thing. one second its eating dinner the next 35000 feet plus. the g force would stun it and at the height you would be you would not need birdseye to mess around with your food. instant scoff delivered by air mail. by the wat. what powers your prop in your sketch
