- On 15 November 2002, PanAmSat terminated its contract with Boeing Satellite Systems for the Galaxy 8iR satellite that was almost completed, claiming that Boeing did not comply with the terms of the contract, and requested US$72 million from Boeing to repay previous advances and other costs. The satellite was later converted to the ProtoStar 2 satellite, which was released in 2009, and was acquired that same year by SES which renamed it to SES-7.
