Juan has a new video out. It is 25 minutes long. You can skip the first 5:30. He just gives background on flying various military and commercial aircraft. He is currently rated on the 777 and has flown the 737-800, but not the 737-Max.

I watched Juan’s 3/20 update video today. Those 737 Max accidents didn’t have to happen.
