Boeing on Wednesday met with "more than 200 airline pilots, technical leaders and government regulators" to unveil new fixes to the MCAS software system for its 737 MAX series jet, following new scrutiny and investigations into what caused 2 MAX 8s to crash in less than 6 months, killing a total of 346 people.

Catch up quick: The Maneuvering Characteristics Augmentation System (MCAS) is an automated system Boeing installed to prevent the aircraft from stalling (losing lift) by pushing the plane's nose down in particular circumstances. A malfunction with this system, where it appeared to activate based on faulty readings from a flight sensor, is the suspected cause of both crashes.

Details of the updates, per Boeing's website:

  • The MCAS will now compare inputs from both angle-of-attack (AOA) sensors. If the sensors disagree by 5.5 degrees or more with the flaps retracted, MCAS will not activate. An indicator on the flight deck display will alert the pilots.
  • If MCAS is activated in non-normal conditions, it will only provide one input for each elevated AOA event. There are no known or envisioned failure conditions where MCAS will provide multiple inputs.
  • MCAS can never command more stabilizer input than can be counteracted by the flight crew pulling back on the column. The pilots will continue to always have the ability to override MCAS and manually control the airplane.

What's next: Boeing plans to send the software updates and new plans for pilot training to the Federal Aviation Administration for review by the end of this week, according to CNBC.

  • Reality check: The new updates are nowhere near close to getting certified, given there numerous ongoing investigations by multiple U.S. and international agencies.
  • The FAA itself is currently under scrutiny for not grounding the 737 MAX jets faster and for delegating certification activities to Boeing.

Overturning Roe could strain abortion access even in blue states

If the Supreme Court overturns Roe v. Wade, abortions could be harder to access even in states where they remain legal, because those clinics could be flooded with patients from states that have cracked down.

The big picture: This has happened before, and clinics fear the crush of demand would be a major problem in the immediate wake of a decision that would allow states to ban abortion.

A critical race theory founder says he's being inundated with threats

Richard Delgado, one of the founders of the critical race theory movement, tells Axios he and his wife have been receiving a steady stream of threatening messages since the coordinated, conservative campaign against critical race theory began.

Why it matters: Educators across the country — even some elementary school teachers — have faced harassment and threats over the past year over lesson plans that teach about system racism in the U.S.

Burnout, money, concern drive Harris turnover

Burnout, better opportunities and concern about being permanently branded a "Harris person" is driving some of the turnover in Vice President Kamala Harris's office, people familiar with the situation tell Axios.

Why it matters: Harris is not only a heartbeat from the presidency but, by virtue of her office, the presumed 2024 frontrunner if President Biden doesn't seek re-election. There's been an inordinate amount of disarray — and, now, turnover — throughout her tenure.
