Well,that is unconfirmed. I don't really get the question,either.
But,this might answer it:100s of flights take place all around the world every day of every second.So,you would never have a sky that is plane-free.So,that means palnes can be inside tornadoes all the time.This can be common.
About 700 Tornadoes have hit planes in the USA.
About 8000 Tornadoes have hit planes Worldwide.
8000 tornadoes might seem alot of tornadoes.But that is nothing compared to hundreds of thousands of tornadoes that have struck the entire planet
