Which has the better flight record, the overengineered commercial jets or the smaller general aviation planes that depend more on the pilot’s skills?
That’s an easy answer to the (obvious) question that you DIDN’T ask:
The original Boeing 737 does. It may be most reliable commerical jetliner ever made.
No doubt that is why the new plane was dubbed the “737-MAX”.
It is becoming obvious that the new model has some serious unintended “bugs”. Just look at the anonymous pilot reports that were discussed in today’s Dallas News story. The FAA needs to ground them until these have been thoroughly investigated and any problems corrected.
