Or pay for a helicopter tour. You can get a ~10 minute helicopter tour for under $100 where I live. They don't fly incredibly high, but given that the minimum safe altitude is 1000 feet in some cases:

Or, just book a flight on a commercial airliner, which is also cheap but doesn't get you a panoramic view. But you'll get way higher than 1875 feet.

Hah, I hadn't considered that!

Probably a skydiving trip would be a better plan then. I've never done it but it seems you jump from a decent height (13K feet or 4km -- so says https://adventure.howstuffworks.com/skydiving1.htm ) because they want to give you some good freefall time.

But I suppose the truly dedicated flat earther will find a way to dismiss that too.
