Famos F-16 inversion bug

"Apparently a problem in the navigation software inverted the [f-16] aircraft whenever it crosssed the equator. Luckily it was caught early in simulation testing and promptly fixed. In the July issue, J.N. Frisina at Singer-Kearfott wrote to Mr. Neumann, 'concerned that readers might have mistakenly believed there was a bug in the flight software, which was of course not the case.'

Mr. Frisina wrote: 'In the current search for reliable software, the F16 Navigation software is an example of the high degree of reliability and quality that can be obtained with the application of proper design verification and testing methodologies. All primary misison functions were software correct.'"
