JAKARTA (Reuters) - Mechanical and design issues contributed to the crash of a Lion Air 737 MAX jet last October, according to Indonesian investigators' briefing to victims' families on Wednesday ahead of the release of a final report.

Contributing factors to the crash of the new Boeing Co airplane, which killed all 189 people on board, included incorrect assumptions on how an anti-stall device called the Maneuvering Characteristics Augmentation System (MCAS) functioned and how pilots would react, slides presented to the families showed.

(Note that CNET may get a share of revenue from the sale of products referenced on this page.) That's more or less comparable to competitors such as Logitech's G502 Lightspeed Wireless and G Pro Wireless ($150) or the SteelSeries Rival 650 Wireless ($120). For comparison, the wired Viper is $80 (£80, AU$135).

The slides also said reliance on a single angle-of-attack sensor made the system more vulnerable to failure, and that the sensor on the aircraft that crashed had been miscalibrated during an earlier repair.

Boeing CEO Dennis Muilenburg continues to face questions about whether the company failed to ensure the 737 Max aircraft was safe and pilots were properly trained. "We are deeply, deeply sorry, we'll never forget and I want you to know that and we're committed to making the improvements we need to make," he said in his opening statement to the House Transportation Committee.
