Redditor sarafina_312 noticed this huge cargo plane at Nashville International Airport today:
It’s an Antonov 124, one of the largest planes in the world. Another redditor, Nozombz, confirmed that it’s probably there to pick up airplane parts from Vought Aircraft:
You are correct that they ship wing panels out on it. I used to work at Vought and they did wing panels for the Airbus 380 and would fly them to France. They would just pull in the trailer and ship it all.
