Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Boeing faces fresh questions about the safety of its aircraft after an engine fire on a transatlantic flight from Edinburgh caused an emergency landing soon after takeoff.

Flames were seen by passengers briefly shooting from the engine of a Delta Air Lines 767 soon after it took off for New York in February last year, after a turbine blade broke off during takeoff.

The flames subsided while the plane was airborne but it made an emergency landing at Prestwick airport south of Glasgow, where ground crew noticed fuel leaking from the plane’s right wing.

The Air Accidents Investigation Branch, the UK government agency that investigates aviation safety, has written to the Federal Aviation Administration in the US asking it to take action with Boeing, which has its headquarters in Virginia.

Metals are made of crystals, they usually defourm along the grain boundaries and fatigue cracks also grow along them. By eliminating those boundaries you reduce the chance for fatigue cracks and make the overall blade stronger.
