British Airways pilot en route to Dubai films the moment Iranian rockets are fired

I think you are correct that it is near Shiraz, and that you are looking at the lights of the city in the distance, however, matching it up in Google Earth, it looks like the plane is located to the NW of Shiraz, looking back towards the city to the SW. It's hard to know the plane location precisely, but maybe over *approximately* 29°53'10"N, 52°21'23 E. You can make the geometry of the lit-up roads and city match up pretty well if you look to the SW towards Shiraz from there. Based on the view from that position, the underground missile base you are talking about should be located in the mountains to the left of the view (to the N of Shiraz), whereas the missiles look like they're being launched from the other side of Shiraz to the south of it somewhere. At first I was thinking at the Shiraz International Airport, which appears to be dual-use (civilian + military aircraft and reinforced hangars), which would be a rather ... bold ... place to launch from, but the location doesn't quite match. Instead, I think it is in the hills to the S of Shiraz where there is a valley where "someone" has been digging an awful lot of tunnels in the side of the mountain and filling up the valley with the rubble from the excavations. There are multiple "drive in" tunnel entrances along the steep valley walls. [about 29°27'35.50"N, 52°29'23.50"E](https://www.google.com/maps/\@29.4599256\,52.4897906\,293m/data\=\!3m1\!1e3) It doesn't look like a mining operation in the conventional sense, because there's no ore processing, a cement plant, or anything like that. Only a big strip of freshly crushed rubble piled in the bottom of the valley to form the road bed.
