I just watched the whole vid, Apparently this is the second airplane crash of the same type - Boeing 737 Max( simply a newer version, not much difference to the old one).
This plane that crashed was only delivered last year November (it's been in use for only 5 months) to Ethiopia. They have a brand new fleet of ships, I'm not sure if all are the 737 max - this type is apparently good for short haul flights. Most likely a wide range of different planes.
Apparently not all planes are suitable for all airports. Ethiopia's airport is very hot and very high in altitude, so the type of planes they chose are based on specific needs and requirements. The planes they choose must demonstrate reliability over a long period of time and showcase efficiency and effectiveness in the airport. However Ethiopia airlines, are apparently the best in the continent.
Imo, they must discontinue this model (737 max) and find out what issues exist within it.
