The barrel roll by the plane could have been done to avoid enemy fire, and to drop a sonobuoy when it was so close to the water. We wouldn't have seen it in the video since sonobuoys can be fist sized. Also, the conversation with Rich included a mention of an orca and it's baby, which triggered my memory of POTUS meeting with the Navajo code talkers. Notice the correlation between words Q has used and Navajo code and how they fit with this incident!
