What an Awesome view
Probably better than most museum visitors get in person
that is a huge facility, very interesting vantage point, thank you for sharing with us.
I just recently bought a DJI Tello drone, got it for a song paid $100 from Facebook market place, came with 4 battery's. It weighs about 80 grams, flight time is 10 to 13 minutes has fpv camera 720p Live View is not to shabby and it is so easy to fly, quite literally press button for take off and it will sit there totally stable. One of the best fun toys I have. Free app to download and you can do indoor shots like the one above.
The technology of tiny drones nowadays is so amazing, I will be upgrading mine and buying a Dji Mini, which is no bigger than the one I have now, has gps a couple of klm range 30 minutes flight time etc etc. I sold myself when I saw how easy the tello was to fly. The guy that sold it to me flew his for a few times saw it was easy and just bit the bullet and ordered himself a bigger one.
Check out the tello,
