I worked at lockheed for my first job as well. I found the flexible schedules to be great but less productive so I understand why others don't support it. Most of the engineers I worked with seemed to not be great at staying productive on 9 or 10 hour days any more then they were at 8 so I'd call it a net loss for the company. Honestly though there is so much bloat at defense contractors it doesn't really matter for them.
