Dame Vera Lynn. I also remember that song from the movie " Dr Strangelove" a perfect backdrop song for a very breezy DBHF

NASA’s Voyager 1 Has Resumed Sending Engineering Updates to Earth: Presumably, Milly and Laura's father is grinning ear to ear from his perch atop Mt. Vision.
After some inventive sleuthing, the mission team can — for the first time in five months — check the health and status of the most distant human-made object in existence.
For the first time since November, NASA’s Voyager 1 spacecraft is returning usable data about the health and status of its onboard engineering systems. The next step is to enable the spacecraft to begin returning science data again. The probe and its twin, Voyager 2, are the only spacecraft to ever fly in interstellar space (the space between stars).
Voyager 1 stopped sending readable science and engineering data back to Earth on Nov. 14, 2023, even though mission controllers could tell the spacecraft was still receiving their commands and otherwise operating normally. In March, the Voyager engineering team at NASA’s Jet Propulsion Laboratory in Southern California confirmed that the issue was tied to one of the spacecraft’s three onboard computers, called the flight data subsystem (FDS). The FDS is responsible for packaging the science and engineering data before it’s sent to Earth.
The team discovered that a single chip responsible for storing a portion of the FDS memory — including some of the FDS computer’s software code — isn’t working. The loss of that code rendered the science and engineering data unusable. Unable to repair the chip, the team decided to place the affected code elsewhere in the FDS memory. But no single location is large enough to hold the section of code in its entirety.
So they devised a plan to divide affected the code into sections and store those sections in different places in the FDS. To make this plan work, they also needed to adjust those code sections to ensure, for example, that they all still function as a whole. Any references to the location of that code in other parts of the FDS memory needed to be updated as well.
The team started by singling out the code responsible for packaging the spacecraft’s engineering data. They sent it to its new location in the FDS memory on April 18. A radio signal takes about 22 ½ hours to reach Voyager 1, which is over 15 billion miles (24 billion kilometers) from Earth, and another 22 ½ hours for a signal to come back to Earth. When the mission flight team heard back from the spacecraft on April 20, they saw that the modification worked: For the first time in five months, they have been able to check the health and status of their spacecraft.
During the coming weeks, the team will relocate and adjust the other affected portions of the FDS software. These include the portions that will start returning science data.
Voyager 2 continues to operate normally. Launched over 46 years ago, the twin Voyager spacecraft are the longest-running and most distant spacecraft in history. Before the start of their interstellar exploration, both probes flew by Saturn and Jupiter, and Voyager 2 flew by Uranus and Neptune.
Caltech in Pasadena, California, manages JPL for NASA.
After receiving data about the health and status of Voyager 1 for the first time in five months, members of the Voyager flight team celebrate in a conference room at NASA’s Jet Propulsion Laboratory on April 20.

This troll living under the Aurora Bridge in Fremont, Seattle, is significantly larger than the Bay Bridge troll, which is only 26" and hard to spot unless you look in the right place as you pass beneath on the east side of Yerba Buena Is.. The Bay Bridge troll is there to protect the new span from earthquakes....

Excitement yesterday on Tomales Bay as a Flying Scot, crewed by 4 experienced Inverness Yacht Club members, turtled during a spinnaker jibe in 20-25 knots of wind and adverse ebb tide. With water temp at 46 degrees, it was fortunate Sonoma County Helo Rescue was simultaneously conducting a demo at the Fisherman's Festival in Bodega Bay, 12 miles north.
The helo crew diverted from the Festival and in 7 minutes proceeded to individually lift the FS crew aboard their helo, which then lowered them into a private residence backyard in nearby Marshall. Reportedly, the surprised residents turned to with blankets and towels and everyone warmed up until the ambulance arrived. The ambulance was the only local vehicle big enough to carry the crew back to their gear and hot showers at IYC.
Meanwhile, the National Park Service hooked a line to the capsized FS, and towed her through the mud to the beach at Marconi, where she was lashed to a telephone pole for the night.
Happy ending is the FS was retrieved today and is now safely back on her trailer with only minor damage.
Talk about West Marin hospitality! We're impressed.

I am curious to know who sent the first Mayday to who and by what means?
My understanding is someone onshore notified the fire department. A fire department member, TF, immediately boarded his rescue Whaler at IYC to go to the scene of the capsized boat, which he could see with his powerful binos. However, the tide was low enough that TF was unable to get underway in the mud. It was about this time providentially the Sonoma County rescue helo, Henry 1, flew on the scene and found 2 crew on the overturned hull and 2 in the water.
From local measurements made at the time, windspeed was 22 gusting 27 knots, water temp was 46 degrees, and air temp was 57 degrees. The capsized Flying Scot crew were likely wearing foulies, but unlikely had on wet suits.
There are no hard and fast figures as to time of onset of hypothermia. But my guess is the Flying Scot crew were nearly there. Maybe Milly can ask them. Personally, I have been in similar conditions on a capsized catamaran and was beginning to go hypothermic after 20 minutes of being wet in 20 knots of wind. This was most noticeably affecting my decision making.
We were able to right the cat after 15 minutes, but the hulls were full of water and the deck awash. I should have anchored the cat instead of trying to steer for the Santa Cruz Harbor Entrance, distance .5 mile, under bare poles. As it was, I was ordered off the boat by law enforcement before I had time to anchor, leaving WF to drift towards Black's Point where she was anchored by friends in a Boston Whaler.

Norton Smith, winner of the first SHTP in 1978, continues his adventures. His C&C 40 CHEETAH is currently on passage from French Polynesia to Rarotonga in the Cook Islands with a crew of 3. Their last port of call was Maupiti, west of Bora Bora, where they ascended to the top of Maupiti, as evidenced by photo below.
We remember in the '78 SHTP Norton's autopilot failed the first night and he skillfully resorted to sheet to tiller steering for the remainder of his race. Ironically, his current autopilot drive onboard CHEETAH failed shortly after leaving Maupiti and they have substituted the emergency tiller while removing the steering wheel in attempts to make repair.

Apologies for butting in on the AIS requirement discussion. But there is something cool going on across the Bay, atop UC Berkeley's 300' Campanile bell tower to be exact. There, since 2016, a pair of Peregrine Falcons have been nesting, making a whole bunch of baby falcons, 3-4 a year.
I encourage you to check out this operation, and the current 4 chicks. They're a hoot..

And the falcons even have t-shirts:

Steady as she goes here at CBC as sleddog weathers the challenge of "high risk" prostate cancer. Apologies for silence. 28 sessions of radiation (now complete) and side effects of hormone deprivation therapy have left little time or energy for SSS commentary, much less strength and agility for racing 110's on Tomales Bay. I have been able to continue daily paddling off the Santa Cruz coastline, and the exercise, clean air, and expansive views has been most therapeutic. If anyone has questions regarding this ongoing health challenge, I am most happy to field emails (skipallanatsbcglobaldotnet) or calls (no texts) to eightthreeone, 47five, zero27eight.
Further north, the R2AK starts this Sunday, June 9th, from Port Townsend. Good luck to all!
