I had a ferry flight that went out of service when a maintenance discrepancy was submitted. Maintenance at their departure airport told them they were good to go with the ferry permit; but they were not yet returned to service through the Logbook. I didn't notice that they had taken off yet; but when the maintenance release form came through; I realized they were already in the air.I was not aware that the origin Maintenance had told the CA (Captain) he was good to go; and I was not watching as closely as I could have been to make sure he knew he was still out of service. I assumed he would know to wait for the in service message; but with a ferry flight; many pilots often get confused on the policies/procedures.There should be more clear guidance to pilots about non-routine flights; like test flights and ferry flights; that they need to be showing in service before departing; no matter what Line Maintenance or Maintenance Control tells them. The only thing I could have done differently is make sure the CA was aware that he needed to be in service in an maintenance release form status.
We departed ZZZ ferrying an un-airworthy aircraft; due to maintenance; with a ferry permit in 'OTS' (Out of Service). Dispatch sent us a message saying we had taken off in OTS and that a report would be filed.We took off from ZZZ because the Captain had been told by Maintenance Control and Dispatch in a conference call that the plane had a ferry permit and that we were safe to depart. In addition; a member of the maintenance staff in ZZZ came out to the aircraft and told us that we were 'good to depart'. Since we're flying under Part 91 with a ferry permit and we had a valid release we believed that to be the case and taxied our aircraft to depart ZZZ.There needs to be better communication as coordination between Maintenance Control; Dispatch and the flight crew during repositioning and ferry flights.
Air carrier Dispatcher and flight crew reported aircraft was ferried despite not being returned to service.
