The guy is truly nuts:

Since taking office I have been very strict on Commercial Aviation. Good news - it was just reported that there were Zero deaths in 2017, the best and safest year on record!

Uh, Donald? Hate to break it to you, but:

Nobody died in a crash of a United States-certificated scheduled airline operating anywhere in the world in 2016.

This probably should no longer qualify as “news.”

That’s because it is the seventh straight year that nobody died in a crash on a United States-certificated scheduled airline operating anywhere in the world.
