Yes. The 737-800 is a Boeing from a different era. Proper engineering.

[sschueller]

But it was built 3 years ago. Does proper engineering prevent future failures if the assembly process becomes flawed at a later time?

For example using cheaper materials, ignoring cracks, not properly training new employees etc.

...stray tools forgotten in the airplane after assembly, metal shavings close to cables... yeah, I read those articles too. However, the fact that the Iranian authorities already concluded that the cause was "engine failure for technical reasons" seems a bit suspicious.

[Fjolsvith]

Are stray bullets or missiles considered technical enough?

> Does proper engineering prevent future failures

No. Never.

The plane could have had a defect. The parts could have had a defect. Maintenance could have caused damage.

Or, the machine was perfect. It just hit the wrong number of birds at the wrong angle. Or experienced one of countless random errors that can take down a good plane.

(It could also be malice.)

Yeah at this point no one knows anything except the plane crashed.

[mulmen]

What does this kind of baseless speculation accomplish?

[Razengan]

What is accomplished by downvoting and attacking people for asking questions instead of answering them?
