Regardless of what is working well (or not) at the moment, once successfully in-flight I'm continuously amazed at what has been accomplished with topography around the world.  It is rare that I don't see something unique or interesting on a flight.

On a recent flight from Brazil to Columbia I glanced down and saw the following:

At first glance it appeared to be a very large plateau - I wondered for a second whether the sim was mistakenly adding snow to the side of the plateau?  When I looked closer, I thought that it might be water going over the side (a very large waterfall, considering I was at FL280).  I noted that my position was to the east of Amazonas, Venezuela so I took a look online and found the following:

Angel Falls - It is the world's tallest uninterrupted waterfall, with a height of 979 metres (3,212 ft) and a plunge of 807 m (2,648 ft). The waterfall drops over the edge of the Auyán-tepui mountain in the Canaima National Park (Spanish: Parque Nacional Canaima).

Amazing... I've noted it as a prime location for some low-level bush flights in the future so I can really check it out.

good catch!
