I believe that at the Software Engineering Symposium at Goddard last year 
there was a report on the reponse of the various NASA Centers on this issue.
There was support from most centers that ADA should be adopted but the primary
real time shops wanted both C and ADA adopted.  If I can find my notes from
that conference I can get more info (as in why the various centers diagreed).

I recall that the majority of the centers, while in general support ADA, wanted
to evaluate the impact of the adoption of ADA before doing so.
