Alaska Airlines says its operations have resumed after it had to ground its planes for hours because of an information technology outage. The airline says in a statement Friday that 229 flights were canceled because of the outage and that more flight disruptions were expected as it works to “reposition aircraft and crews.” It also adds it is working on getting travelers affected by the disruption to their destinations and recommends that passengers check their flight status before heading to the airport. The grounding Thursday affected Alaska Air and Horizon Air flights.

The National Transportation Safety Board says faulty engineering led to the implosion of an experimental submersible that killed five people en route to the wreck of the Titanic. The NTSB made the statement Wednesday in its final report on the hull failure and implosion of the Titan submersible in June 2023. Everyone on board the submersible died instantly in the North Atlantic when Titan suffered a catastrophic implosion as it descended to the wreck. The NTSB report says the faulty engineering of the Titan did not meet necessary strength and durability requirements. The implosion led to lawsuits and calls for tighter regulation of private deep sea expeditions.
