  • US court asks India to pay $132 million to Deutsche Telekom in Devas Antrix case
  • Don’t ask me to explain this. The Devas Antrix legal case has been wandering through various international courts since 2005, and I have never been able to find a clear explanation for the court battles. What I do know is that it involves Antrix, what was then the commercial arm of India’s ISRO space agency, and a number of international companies, all of which have sued when the project was canceled.

 

Boeing’s problems are only the tip of the iceberg

Most of all beware this boy.’
As noted by the Spirit of Christmas Present in Dickens’ The Christmas
Carol
, ‘This boy is ignorance, this girl is want. Beware them both,
but most of all beware this boy.’

Since the beginning of this year, following the near disaster when a door of a Boeing 737-Max airline blew off during the Alaska Airlines flight, the media has been obsessed with reporting every single subsequent Boeing airplane incident as attributed to bad management and quality control at Boeing.

The problem with this shallow reporting is that it fails entirely in recognizing the real depth of the problem.

First, in most of the incidents reported, the planes involved were not recent purchases from Boeing, but had been owned by the airlines for years, sometimes decades. Thus, any maintenance issues, such as a wheel falling off after take-off or a landing gear collapsing on landing or the sudden failure of an Airbus plane’s hydraulic system, are not Boeing’s fault, but the fault of the airline the plane belongs to. In the case of these particular incidents, that airline was United, and in every case, the failure was with its maintenance department, not Boeing’s bad management and poor quality control.

A similar string of incidents has also occurred at American Airlines, involving both Boeing and Airbus airplanes. With both United and American, evidence suggests that the quality of its maintenance staff has likely declined significantly since 2020, when both companies decided to abopt Diversity, Equity, and Inclusion (DEI) hiring practices, which made skin color and sex the most important qualification in hiring, rather than talent, skill, experience, or knowledge.

It is important for readers to recognize this fact when they see new stories about a Boeing plane forced to make an emergency landing, such as the story today about a United Airlines’ Boeing 787. It apparently had a cracked windshield, requiring an unscheduled landing in Chicago. The article at the link focuses a great deal on Boeing, but the focus should instead be on United Airlines, not the airplane maker, since it is United’s responsibility to keep its fleet flightworthy. When an airline fails to do so, future customers should take note, and consider other options when they need to fly.

In other words, you shouldn’t avoid flying on a Boeing plane, you should avoid flying on airlines that maintain their airplanes badly.

Having said this, I don’t want my readers to think I am trying to let Boeing off the hook. Far from it. » Read more

Interacting galaxies

Interacting galaxies
Click for original image.

Cool image time! The picture to the right, reduced and sharpened to post here, was taken by the Hubble Space Telescope as part of a dark energy survey. It shows two galaxies very close together, their perpheries only about 40,000 light years apart, with the larger galaxy about the size of the Milky Way.

For comparison, the Large Magellanic Cloud (LMC) is about 167,000 light years from the Milky Way, more than four times farther that this satellite galaxy. Yet the satellite galaxy here appears much larger than the LMC, having a central core that the LMC lacks. From the caption:

Given this, coupled with the fact that NGC 5996 is roughly comparable in size to the Milky Way, it is not surprising that NGC 5996 and NGC 5994 — apparently separated by only 40 thousand light-years or so — are interacting with one another. In fact, the interaction might be what has caused the spiral shape of NGC 5996 to distort and apparently be drawn in the direction of NGC 5994. It also prompted the formation of the very long and faint tail of stars and gas curving away from NGC 5996, up to the top right of the image. This ‘tidal tail’ is a common phenomenon that appears when galaxies get in close together, as can be seen in several Hubble images.

In this single picture we are witnessing evidence of a process that has been going on for likely many millions of years.
