Groundbreaker project by NSA

In 2001 NSA transferred large number of employees from their pay-roll to private contractors. Needless to say number of employee transferred in secret and contract was 2billion worth at the time of estimation. According to 'Shadow Factory' 35 contractors shared this contract.

Basically employees sat on the same chair but got paycheck from different company.
