United’s 737 MAX 10s: 300+ Hours Flown And Still No Passengers

It’s no secret that several of Boeing’s latest models of commercial aircraft are going to enter service many years behind schedule, with delays plaguing the certification of both thenarrowbody 737 MAX 7 and 10 models and the widebody 777X family. What makes this situation especially complex is the fact that many of these aircraft have already been built, with, for example, 26 widebodies from the 777X family having been produced to date.
