> 737 and other Boeing models have been flying for decades and are a very safe airplanes overall with a very well-known loss risk profile. This is the catch, though. The 737 MAX is a 737 in name only. It's a bit of a ship of Theseus design, because Boeing management didn't want to take on the cost and time to build a new plane from the ground up. The company was under pressure from the A321neo and wanted something fast. Certifying a new aircraft also takes time and money. By altering a 737 Boeing was able to claim it was still a 737 and retain the type certificate and, important for the airlines buying it, not have to retrain pilots on a new type. Like many other things in creaky corners of the commercial passenger airline industry, the foundation is from the 1960s. Solid and appropriate for the time, it's now aged and unsuitable for modern applications. Like building an extra story on a house with a foundation made for a single story, the compounded risks introduce so many unknowns as to make it impossible to calculate the real risks. Insurance companies should look at the MAX again and consider whether or not it deserves to be classed in the same risk profile as the 737 type.
