It sounds like the altitude existence assumption caused cascading errors which in turn exhausted the system memory.

- ars 12y agoThat's not what the article said. They said that since it didn't know the true altitude the computer assumed the plane could be at every altitude, and checked every single possible one. This was made worse by a flight plan that had the plane going in and out of the area, so there were a tremendous number of permutations of possible flight paths. The computer attempted to allocate memory to calculate every one of them and ran out of memory.
