YU55 Near Miss

I dare to ask about the consequences of an eventually failing asteroid observation software.

I think the good news is that there are a lot of amateurs out there who will use a broad variety of similar tools which calculate and “estimate” the same thing. If one of those tools fails, there is still a bunch of others who do it right.

Redundancy is the key to success sometimes. We usually try to avoid this in coding, but it has its place for instance at safety critical applications. But still, it needs a brain, common-sense and - believe it or not - capacity for teamwork, especially if you analyze inconsistent scenarios. Without one or the other, redundancy can also become deadly where it was actually meant to save lives.

The two altimeters in an airplanes cockpit work independent from each other. If one fails, there is still a high chance the other works. But if a hard-headed doesn't take into account that it may be HIS altimeter which fails and not the one of his co-pilot, then it may end up in a disaster like the one in 1990 where the DC-9 was flying about 900 feet (275 m) too low during approach and then hit high ground at Stadlerberg, near Zurich, Switzerland.


  1. I agree that teamwork is essential in any field and one can not achieve alone what he can achieve in a team or group.As they say" none of us is as smarter than all of us". I am in conformity with your argument.

  2. I'd like to use some of your cartoons in a presentation. How can I obtain the necessary rights? Many thanks in advance!

  3. Hi idealist01, Did I ever respond to your question? If not, please excuse my poor response time. You can take any of the cartoons from the blog as long as you don't earn any money with it.
