There are more delivered 737's than any other commercial aircraft, ever.

TBF 737 and 737-NG are quite safe (look at page 10 here and consider that 737s make up a pluarlity of commercial aircraft), crashes like this one can happen with pretty much any aircraft type. 737 MAX is another story, obviously corners were cut in the name of profits at the well-known cost of human lives. (in short, fuck Boeing, not only for 737-MAX but also for their weapons manufacturing)

I think you're thinking of the 787.
