737 is an obsolete design. It's been outdated since the 90s, and obsolete for at least a decade now. It's not just the max disaster. There's was the rudder handover disaster which led to 2 crashes back in the day. It's system design is woefully inadequate in today's design standards. It's a 60 year old design and technology airplane. It's the best they knew back then. It's ridiculous to still insist on what's clearly superceded since the 80s when 757/767 design was out. The 320 at least is 30 year old design and technology, not 60. The aerodynamics of the 737 is the very first design boeing had, IN THE 1950s. The 720 model which later became the 707. Those crude flat panel windshields because they couldn't make aerodynamics curved ones back then. The same too narrow by today's standards fuselage. No EICAS which is a huge improvement to safety and efficient identification of system status and failures. That ridiculous electric stableizer team with its 2 miles of cables instead of a much more reliable hydraulic trim system which is what boeing designed for its newer designs. The list is long. I could go on and on. And don't tell me it's so reliable. It isn't. You just don't know what's failed or about to fail because it doesn't have a monitoring system like the later boeing and airbus designs. No systems self test in the background, no status messages.

Whoever decided to order these things for the last 20 years should give their bonuses back. Especially the max order decision. This has greatly crippled the united next plans which is no doubt damaging financially.

The 320 should have been ordered instead of 737 max and 350 should have been in the mix with the 787, it's one gouge heavier longer range airplane the 787 just can't match.

Bad decisions have consequences. We're feeling those consequences today.

Look at Lufthansa. They have a wide mix of aircraft and no problem making money with each and every one of them. Always the right fit aircraft on the right market route. None of this less fleet types to an extreme is more efficient is correct. It's nonsense.
