I have had considerable experience in space launch and was part of a team that developed the FAA/USAF safety standards. I do not know exactly what occurred here, but you need to realize that launches from Cape Canaveral and Vandenberg AFB involve the use of government operated ranges that mandate and express permission to launch. The SpaceX launch facility at Boca Chica is a privately operated range. It is not hard to imagine that data was uncovered related to the previous launch that concerned the FAA. For example, suppose the winds data showed that debris from a launch failure could have endangered populated areas. At the Cape or VAFB the USAF would have assessed the situation and not allowed the launch to proceed - we have done that. At Boca Chica the FAA is relying on SpaceX to do that.
Airliners are not required to operate from airports with control towers, but suppose the FAA found that an airliner had violated safe practices by not announcing its approach on the CTAF or proceeded to land even though there was already an aircraft on the runway. Don’t you think that the FAA might shut down the airline operations at that airport - if not everywhere - until they were satisfied that operations would be safe?
Back in the early 90’s there was a Pegasus launch that was being supported out of the Cape and Wallops FF. The aircraft was just about to launch the Pegasus when data was lost at WFF. The aircrew made a decision to launch anyway, since aborting the launch after battery activation would have caused an extended delay, and WFF was really not needed anyway. There was an NTSB investigation into why the launch occurred even though the organization supposedly running the operation lost their data link.
