Perhaps the following table from
http://www.rtcgroup.com/cotsjournal/cots7800/cots7800p60.html might be of
interest when you discuss the costs of using Ada. BTW Don't expect better
numbers from C++.

|language | Lines /| Errors /     | Time /  | Total /       |
|         | Error  | 10,000 Lines | Error   | 10,000 (hours)|
|---------+--------+--------------+---------+---------------|
|  Ada    |  270   |      37      |  20 min |  12.35 hours  |
|---------+--------+--------------+---------+---------------|
|   C     |   80   |     125      | 240 min | 500 hours     |
+-----------------------------------------------------------+

Remember time is subjective. You don't really know how much time you spend
unless you measure.
