Flawed analysis, failed oversight: How Boeing, FAA certified the suspect 737 MAX flight control system
omg this article is absolutely horrific. Boeing are in deep shit if this is borne out.
Like all 737s, the MAX actually has two of the sensors, one on each side of the fuselage near the cockpit. But the MCAS was designed to take a reading from only one of them.

Lemme said Boeing could have designed the system to compare the readings from the two vanes, which would have indicated if one of them was way off. Alternatively, the system could have been designed to check that the angle-of-attack reading was accurate while the plane was taxiing on the ground before takeoff, when the angle of attack should read zero.

“They could have designed a two-channel system. Or they could have tested the value of angle of attack on the ground,” said Lemme. “I don’t know why they didn’t.”

The black box data provided in the preliminary investigation report shows that readings from the two sensors differed by some 20 degrees not only throughout the flight but also while the airplane taxied on the ground before takeoff.

Several Boeing 737 Max 8 pilots in U.S. complained about suspected safety flaw | Airlines | Dallas News
'one captain calling the flight manual "inadequate and almost criminally insufficient"'

'The disclosures found by The News reference problems during Boeing 737 Max 8 flights with an autopilot system, and they were all during takeoff and nose-down situations while trying to gain altitude.'

AMERICAN AIRLINES 737MAX8: “LIKE A FLYING PRISON”
Quite unusual to see an honest review of travelling coach-class on an internal US flight. This is a massive stinker:

“I admit American isn’t my favourite airline, but this has made me seriously re-evaluate ever travelling on them again. And it won’t be economy. If this is Americans idea of their future standards, they can keep it. Aviation enthusiasts might find it really interesting- I felt like I was in a flying prison”.

SCADA systems online, and a horror story about a non-airgapped Boeing 747 engine management system
747's are big flying Unix hosts. At the time, the engine management system on this particular airline was Solaris based. The patching was well behind and they used telnet as SSH broke the menus and the budget did not extend to fixing this. The engineers could actually access the engine management system of a 747 in route. If issues are noted, they can re-tune the engine in air.

The issue here is that all that separated the engine control systems and the open network was NAT based filters. There were (and as far as I know this is true today), no extrusion controls. They filter incoming traffic, but all outgoing traffic is allowed.

satellite rescue abandoned due to patents
'SES and Lockheed Martin explored ways to attempt to bring the functioning [AMC-14] satellite into its correct orbital position, and subsequently began attempting to move the satellite into geosynchronous orbit by means of a lunar flyby (as done a decade earlier with HGS-1). In April 2008, it was announced that this had been abandoned after it was discovered that Boeing held a patent on the trajectory that would be required. At the time, a lawsuit was ongoing between SES and Boeing, and Boeing refused to allow the trajectory to be used unless SES dropped its case.' In. credible. http://www.spacedaily.com/reports/Boeing_Patent_Shuts_Down_AMC_14_Lunar_Flyby_Salvage_Attempt_999.html notes 'Industry sources have told SpaceDaily that the patent is regarded as legal "trite", as basic physics has been rebranded as a "process", and that the patent wouldn't stand up to any significant level of court scrutiny and was only registered at the time as "the patent office was incompetent when it came to space matters"', but still -- who'd want to go up in court against Boeing?

747s using VLANs to secure in-flight access to engine management systems
'I was contracted to test the systems on a Boeing 747. They had added a new video system that ran over IP. They segregated this from the control systems using layer 2 VLANs. We managed to break the VLANs and access other systems and with source routing could access the Engine management systems.' (via Risks)
