All we know for sure is that they are NOT ACKNOWLEDGING that they brought in other assets to scrutinize the goings on.
Also, given all the givens, it is somewhat likely that those pilots etc. and/or others on the carrier were already part of black ops experts on such goings on.
And, at that point in time, such things were really very frequent occurrences. It's doubtful that officials thought much new could be learned from that merely latest of thousands of incidents.
But if you think 3 million Americans were abducted by aliens and then released back into the wild to answer poll questions about it, then I think your mind zigged when it should have zagged.
Nothin' personal, brohaim.
