The 737s are the most common airliner in the world, more than 10000 have been built, and more than 1000 are in the air right now. The pre-MAX 737s are just fine

The 737s are the most common airliner in the world, more than 10000 have been built, and more than 1000 are in the air right now. The pre-MAX 737s are just fine (though it had some issues with the rudder in the 90s, and, well, nearly 2% of all 737s built have been lost (184 hull losses) with nearly 5000 fatalities. Goes to show how much they fly.)
