7. I think from personal experience working on that particular model aircraft for over 25 years

it is the most safest plane flying. I personally would get on that plane now....................

Most people do not think of the fact that the pilots that were in command of those aircraft did not know what the stab trim operation is used for or for that matter how to cut off the system, and they did not even see or look at the instrument panel in front of them (PFD) to show that the AOA had failed on the PFD, while taxing, Lion Air.........................and that the maintenance crews did not do their job properly..........like jacking up the aircraft and performing a "Weight off Wheels" test or WOW.
Lion Air pilots.......they just took off................and realized at 3,000 feet they had oh sh*t moment...............

"A key instrument reading on Lion Air flight JT610 was faulty even as the pilots taxied out for takeoff. "


Lemme;

In his view, it wasn’t a case of Boeing’s design engineers ignoring the consequences of a single sensor failure. “It’s a case of overvaluing the pilots’ response.”

"The data confirms that a sensor that measures the plane’s angle of attack, the angle between the wings and the air flow, was feeding a faulty reading to the flight computer. The two angle-of-attack sensors on either side of the jet’s nose differed by about 20 degrees in their measurements even during the ground taxi phase when the plane’s pitch was level. One of those readings was clearly completely wrong."


I realize that I have cherry-picked the article, but.........................Boeing took a proven design.......................just like every manufacturer does today, from cars to boats and even buildings............................the space shuttle was grounded for over three years (Challenger) and two years respectively (Colombia) and it took off again.....................it was proven design, a very dangerous one........................

But if you have a fault on the Lion Air PFD and did nothing........................that is hard fault.....................
