Collisions At Sea - Not Necessary
The collisions of USS Fitzgerald and USS McCain are still something of a mystery, since the investigations have not been made public. But more and more information has been disclosed.
Most recently, it has been revealed that equipment installed on every ship to avoid collisions by transmitting information to other ships about position, course and speed, has been routinely turned off. As a result, other ships have had difficulty detecting USN ships by radar.
In a recent statement, the Chief of Naval Operations explained that the Navy's stealth technology makes it very difficult for commercial ships to detect its ships by radar or even visually. Apparently, ships have routinely turned off their Automatic Identification System (AIS) even in crowded sea ways. This may explain why the Philippine container ship that collided with USS Fitzgerald knew it had collided with something, but didn't know it was a ship.
It may be that ship personnel turn off the AIS in crowded waters because it frequently sounds an alarm of a pending collision and this becomes annoying. Something of this sort may have contributed to McCain's collision with a tanker in the approaches to Singapore.
According to Congressional Testimony, the Navy will no longer routinely turn off AIS equipment (http://www.professionalmariner.com/Web-Bulletin-2017/After-collisions-Navy-will-turn-on-AIS-in-high-traffic-areas/)
But this can't be a complete explanation for the collisions. My conjecture is that officers of the deck and other bridge personnel have become too reliant on automated radar and steering systems and may not be doing such a simple thing as looking out the window.
I recommend greater emphasis on basic seamanship skills.
Read up,for example, on the Andrea Doria and other examples of collisions at sea.

The First Time I Saw Tampa
The first time I saw Tampa, we were getting ready for war.
It was 1940, I was not quite four years old, but I knew that war was coming. I knew it from the newsreels at the movies. But mostly I knew it because my dad was in the US Army Air Corps, and I saw the P-39's, the P-40's, the B-18's and C-47's flying overhead.
We lived in an upstairs apartment, and Mother sent me down to the front yard every morning to pick a grapefruit for breakfast.
Tampa was a small town. We got around by walking or by taking the street car. Sometimes we would take the streetcar to the end of the line, where we would watch the sea. I was fascinated by the conductor flipping the seat backs in the other direction before starting back the way we had come.
After about six months, we moved to Tallahassee. Another air base. Different airplanes. We were there on December 7, 1941. Moved to Mississippi in 1942 during the war. Didn't get back to Florida until 1969. In 1942, Mississippi was much like Florida - poor, economically backward, racist.
I didn't make it back to Florida until 1969. Operated three ships out of Mayport, Florida.
By 1969, Florida was modernizing and that was a good thing.
Mississippi was another thing entirely.

Puerto Rico, Irma, and International Relations
As Hurricane Irma bears down on Puerto Rico, I am reminded of a friend and shipmate, and also of a blustering captain who may not have been the sharpest knife in the drawer.
It is customary for an officer reporting to a ship to pay a courtesy call on the captain.
In 1957, Navy Reserve Lieutenant Jose Ortega-Otero, a graduate of the United States Merchant Marine Academy, reported to USS Cabildo, where he was to become the Chief Engineer.
When Jose called on the captain, the commanding officer detected an unfamiliar accent.
"Where are you from?" Captain Kelsey asked.
"I'm from Puerto Rico," Jose answered.
"What are you doing in the American Navy?" Captain Kelsey asked in puzzlement.
"I was about to be drafted into the American Army," Jose explained.

Schoolbus History
Interesting event this morning in Oriental celebrating the 100th anniversary of the first public school bus in the state of North Carolina that began operation on this date in 1917.
This was a revolutionary development demonstrating the dedication of the State of North Carolina to public school education in rural areas of the state.
It is a result worth celebrating.
