New Zealand are world leaders in private high altitude aerospace development. Kea Aerospace is another company with aircraft up and running from its base in Christchurch. Clever idea this one; they're making aircraft that fly perpetually, with solar panels charging batteries during the day. Being in the air so long, they can do accurate testing, provide cost-effective communications, you name it. One of the founders is Mark Rocket, who was also a founder of Rocket Lab. Mark Rocket is a clever guy and I've spoken to him previously, he complimented me once by saying I had good ideas (heh).
In the below video at about the 1:03 mark, you can get a good aerial view over Banks Peninsula with Akaroa Harbour on full display. This harbour is massive, you could lose several cruise ships in it, wondering where did they go?
