This video is a news report from "9 News" in Australia. It describes two recent air safety incidents.

The first incident was a bad case of turbulence on an LATAM flight from Sydney to Auckland, in which many people were injured as they were thrown first against the ceiling and then onto the floor. Turbulence is not unusual, especially in that part of the world, and shows why airlines strongly recommend that passengers keep their seat belts fastened while seated (although that wouldn't have helped the poor guy who was injured in the toilet). I feel sympathy for the passengers (those injured and those simply scared), but turbulence cannot be blamed on Boeing. What is much more worrying is the statement by the pilot that all his instruments went dark for a few seconds when the turbulence hit. The times that instruments are most important are when something unusual and dangerous happens, and such a failure could increase the consequences of any incident.

Modern aircraft like the 787 use virtual instruments, where data such as airspeed, altitude etc. are displayed on electronic monitors in the cockpit, rather than on dedicated physical instruments. This has a number of advantages, including better use of the display real estate in the cockpit (instruments can be hidden at times when they are not needed), but also introduces several single points of failure which can cause all instruments to be lost, as in this case. The fact that such a failure occurred simply due to some turbulence is extremely concerning. Turbulence is most common during landing and take-off, and this incident suggests that pilots could lose all their instruments during those critical and high risk phases of the flight.

The other incident involved a United Airline flight from Sydney to San Francisco, this tine on a Boeing 777. The flight turned back due to what appeared to be a leak of hydraulic fluid from the undercarriage which caused smoke to come from one of the wheels. United blamed this on a "maintenance issue". This doesn't appear, at first glance, to be so critical, but on closer inspection is also extremely dangerous. Hydraulics are used to activate brakes, to raise and lower the undercarriage, and most importantly to operate the control surfaces (on the wings and tail) that pilots use to control the aircraft. A leak of hydraulic fluid is therefore potentially disastrous.

So, to summarise, there have been air safety incidents with 737 Max, 777 and 787 aircraft. Personally, I am not eager to fly on any Boeing plane right now.
