Infrared Horizon from 33 000 feet, Astounding Flat Earth Phenomena !

An infrared filter lets us see at incredible distances through smoke and haze from 32 800 feet, all the way out to the horizon it seems. Unbelievable flat earth phenomena, what does all this mean?

edit: 7/26/2018 I'm using a 4k Sony HDR AX53 camcorder, which has the night shot feature, and an infrared long pass filter (IR 950) made my Zomei, but there are other brands out there, search on camera stores or Amazon.
