If memory serves me correctly, one of the concerns during the evaluation
period was that PL/I (and C and other languages) allowed you to shoot
yourself in the foot to some extent. The evaluators were looking to decrease
programming errors so the decision was made to create a new language with
more checks and restrictions, hence ADA was born (I not familar enough with
ADA to say whether or not it met that goal).

It is my understanding that this is true based on informal information at a session
in a conference I went to.
