For US gov't projects, the longer they take and the more they cost, the 
greater the profit for the contractor. Since Ada makes projects shorter 
and cheaper, there are strong market forces against the use of Ada on 
these projects.

For civil aviation products, there are a lot of forces in action. Many 
civil products are based on military products, so one would expect them 
to use the same language as the military product.

For new products, the reasons are different. Language choice is a 
software engineering decision that is usually not made by software 
engineers (usually by managers or coders). They are not going to make 
the correct choice very often. This is no different than a manager 
committing to a schedule and budget before requirements definition takes 
place.
