Plane views - NOT amateur radio

We flew back from Finland yesterday. The weather, and views from the plane, were perfect.

Before leaving, we visited medieval Porvoo about 55km from Helsinki.

Blickling Hall, North Norfolk - NOT amateur radio

Oriental Plane Tree?

This afternoon we drove to North Norfolk to the National Trust property at Blickling Hall. We'd been several times before and only went into the gardens. All the driving really tired me, so I sat on a bench in the shade whilst my wife took photos. I think this was an oriental plane that I sat under. It had seeds a bit like sweet chestnuts but the leaves were all wrong.

An amateur solar plane "satellite"?

Recently, Qinetic managed to keep a solar power plane aloft for 7 days using its onboard navigation to keep it over a fixed location and using solar cells to top up batteries to keep it flying at night. Could such solar powered flying devices could be used as "satellites" flying a few miles above the earth to support amateur VHF/UHF repeaters and experiments i.e. a more sophisticated version of balloon experiments?  See http://www.bbc.co.uk/news/science-environment-10664362 .
