The payload of LASA9 ascended to the edge of space on April 30th and dropped back to the surface of the planet a few hours after launch. During its flight the balloon broadcast messages recorded by students from Perth Ontario (See the Sounds of LASA9 below). Balloon chasers using radio and computers saw on their digital maps the balloon land in what looked like the middle of the St Lawrence River. When they arrived at the river shortly after landing the payload was still sending out radio signals. Using the signal and binoculars they were able to site the payload floating in the river. They were able to contact some local boaters to hitch a ride and recover the package.
