Yes, Mr. Chair, there were fundamentally three areas that we were concerned about. One is the state of the equipment, particularly on the air force side, where we indicated that there are some aircraft that have been used for 45 years, and they are having to manufacture spare parts. So we have significant concerns on the equipment side for the air force.
On the personnel side, we noted that often the personnel who are actually reacting to incidents have to keep working. They don't have time to do their training and that type of thing. They don't have time to take their leave. So the burden is resting with the same people.
Then we noted that the information technology system is aging.
So all three of those together led us to be concerned about the sustainability of the program.
