Flying bananas

How’s this for a truly bizarre project?
For me, this raises a few questions though, the first of which is Why? The second is WHY?
I had a quick look through the site and in the legal bit it says there are basically very few laws that apply for traffic between 25,000m and “space” – but they have to get it to an altitude of 25,000m first.. and then what about it coming back down afterwards? I can just imagine a pilot report seeing a giant banana in their flightpath 🙂
