Glider history made in San Diego’s Point Loma.

Did you know that glider history was made above the bluffs of Point Loma in San Diego?

Two landmark plaques that commemorate this history (which includes the breaking of a sailplane flight duration world record) are located just inside the entrance gate of Cabrillo National Monument. A small dirt footpath leads up to the boulder upon which they are mounted. Beyond, a slope descends steeply to the Pacific Ocean.

I recently walked from the Cabrillo National Monument’s visitor center down to the plaques to have a close look…

The plaque on the left states:

IN COMMEMORATION OF THE EARLY AVIATION PIONEERS THAT FLEW AMERICAN DESIGNED AND MANUFACTURED SAILPLANES IN SAN DIEGO. THESE AVIATORS ARE REMEMBERED BY THOSE WHO FLEW AFTER THEM AND THE CITIZENS OF SAN DIEGO

John C. Barstow – William Hawley Bowlus – Alan R. Essery – Forrest H. Hieatt – Anne Lindbergh – Earle R. Mitchell – Adolph R. “Bud” Perl – William Beuby – Lowell E. Bullen – Albert E. Hastings – I. N. Lawson – Charles A. Lindbergh – Allison J. Moore – William Van Dusen

World-record speed Turbinator in San Diego!

The absolutely fantastic 2001 Team Vesco “Turbinator” is now on display at the San Diego Automotive Museum in Balboa Park!

This amazing 30-foot-long streamliner set the wheel-driven land speed record of 458.440 miles per hour at the Bonneville Salt Flats on October 18, 2001.

Anyone interested in cars, racing, engineering or technology would love to look at this one-of-a-kind speedster. It has a unique four-wheel drive system powered by a 3,750 horsepower engine from a helicopter! Can you imagine sitting in this slender vehicle flying in a blur across the salt flats? It seems a driver would need nerves of steel!

Check out the exhibit at the San Diego Automotive Museum and you can also see owner/driver Don Vesco’s NHRA Lifetime Achievement Award (presented in 2002) and a great video showing his incredible Turbinator in action!

Hammering railroad spikes in downtown San Diego!

When I think of railroad workers manually driving spikes with hammers, I think of black-and-white photographs of workers laying tracks across deserts and mountains in the 19th century. I imagine the hammering of that Golden Spike, joining the rails of the first transcontinental railroad.

Well, here in downtown San Diego, in this high technology 21st century, a group of railroad workers were using spike mauls today to hammer (you guessed it) good, dependable spikes!

Tracks that support the Amtrak Surfliner, North County Transit District’s Coaster, and freight trains are undergoing maintenance this weekend. (I saw a big tamping machine in the distance, which is used to pack ballast under the tracks.)

The last time I saw a person swinging a spike maul, a John D. Spreckels impersonator was hammering a Gold Spike at the 100th Anniversary of the San Diego and Arizona Railway event in Campo. See those fun photos by clicking here!

Autonomous cars test on San Diego streets!

In the past few days, I’ve spotted autonomous Waymo cars navigating streets in San Diego. Bankers Hill is where I saw two of the cars, to be exact. Both had drivers behind the steering wheel. I had my camera at the ready this afternoon to capture the above photo. Yes, there is a driver in there.

Waymo is the company that has those driverless autonomous taxis operating up in San Francisco. You hail them with your phone and input the destination.

Here in San Diego, and other test cities, Waymo cars are being driven through certain neighborhoods in order to gather data, refine maps, and learn about the peculiarities of different places. Here’s an article that thoroughly describes the Waymo tests in San Diego. They began very recently.

I can see how many people are wary of driverless cars. The concept is revolutionary and still pretty new. One hears of glitches.

I suppose, however, that at some point in the future, driverless cars will be ubiquitous in every city around the world and taken for granted, just as other groundbreaking technologies eventually become the norm. I grew up with a rotary dial telephone . . . and an astounding invention: the electronic push button calculator!

We live in exciting, uncertain times when technology is taking gigantic leaps forward. Artificial intelligence, chips in heads, advancing robotics, virtual reality worlds… Where will all of this take us? How will this change us?

I wonder. Will the automation of practically everything make life more fulfilling?

I guess humanity will take the journey and find out…

Doctor Who exhibition coming to San Diego!

Doctor Who and science fiction fans, take note! The exhibition Doctor Who Worlds of Wonder: Where Science Meets Fiction is coming soon to San Diego!

Both fun and educational, the world-class exhibit will open at the Comic-Con Museum in Balboa Park on March 15, 2025.

The museum will be overflowing with iconic props, sets, and behind-the-scenes materials from Doctor Who, the world’s longest-running science fiction television show!

BBC Studios and scientific advisors will help produce an interactive experience that will inspire Comic-Con Museum visitors, as they learn about scientific topics touched upon in episodes of Doctor Who. As a promotional flyer explains: It is a must-see for families, school groups, Doctor Who fans, curious minds and future scientists, whether or not they have seen the TV show.

People I spoke to at the museum today are super excited to be hosting this epic exhibition.

Mark it down on your calendars! I can’t wait!

Epic geocaching event begins in Southern California!

Image credit: Chet Kinzelberg.

An epic multi-month event has begun in San Diego and throughout our region. Geocachers are participating in Cache Across Southern California 2025!

Geocaches are now hidden and waiting for discovery in ten Southern California counties. The event is described in this way:

Cache Across Southern California (CASC) invites you on a thrilling journey through roughly 40 Geocaches hidden across all 10 Southern California counties. With this year’s Hollywood-inspired theme, you’ll explore the magic of filmmaking while embarking on a Geocaching adventure like no other. For those who are unfamiliar, Geocaching is a worldwide GPS-based scavenger hunt in which one uses a free app on their phone to find hidden containers with a log sheet inside. To join the fun, locate a CASC Geocache and print the official passport. Each cache contains a unique stamp, which you’ll use to mark the small movie tickets on your passport. This makes prize redemption at the SoCal Spring Fling Mega Event on May 3, 2025, a seamless experience. As you progress, share your journey with fellow participants in the official CASC Facebook group. The group will also feature updates and announcements leading up to the Spring Fling.

If participating in this epic event sounds overwhelming, fear not. While the top prize requires locating 15 caches across 10 counties, you can also win prizes for finding 6 caches across 3 counties.

Want to join the fun or learn more about the outdoor hobby of geocaching? The San Diego Geocachers Facebook Group is where you can interact with over a thousand other local geocaching enthusiasts.

Happy hunting!

Spanish galleon versus an aircraft carrier!

It’s almost New Year’s Day. It’s one of those days when we pause to think about the passing of time.

During a walk along San Diego’s Embarcadero this morning, I took these interesting photographs. They demonstrate how human technology has advanced over the course of five hundred years.

A replica of the 16th century Spanish galleon San Salvador (the ship sailed by explorer Juan Rodríguez Cabrillo when he “discovered” San Diego Bay), built by the Maritime Museum of San Diego, was crossing the water. Just beyond were two active U.S. Navy aircraft carriers docked at NAS North Island: the USS Abraham Lincoln (CVN-72) and USS Theodore Roosevelt (CVN-71).

So how do these very different ships compare?

The historic San Salvador galleon was about 100 feet long. The two Nimitz-class aircraft carriers have a length of 1,092 feet. That’s more than ten times the length of an old Spanish galleon.

A galleon, built primarily of wood, would have a displacement weight of about 200 tons. The gigantic, mostly steel aircraft carriers? Their displacement weight is 116,800 tons–that’s 584 times heavier!

A Spanish galleon could travel at a maximum speed of around 8 knots (under ideal wind conditions). These enormous, nuclear powered aircraft carriers can travel at a speed over 30 knots, no matter the weather, without refueling for 20–25 years!

Today technology is progressing at a mind-boggling rate. Is it possible to imagine the distant future? In another five hundred years, will an advanced civilization still need or have ocean-going ships?

Only time will tell!

Happy New Year!

San Diego’s first Smart City touchscreen kiosk!

San Diego’s first Smart City touchscreen kiosk was installed last month in downtown, on the corner of Fourth Avenue and B Street. I encountered it for the first time several days ago during a walk!

The big, bright, digital touchscreen kiosk provides information in a way that might remind you of your smartphone. All sorts of great up-to-date information is available for tourists, residents, those who work or play downtown, and even those who are homeless.

The kiosk I observed is the first of 50 that are planned for downtown San Diego! The project is made possible by a partnership between the City of San Diego, IKE Smart City, and the Downtown San Diego Partnership.

Not only do these high-tech kiosks provide passersby with transit updates, event information, city attractions, maps, services and more, they provide free Wi-Fi!

I spent a few minutes goofing around with this first downtown kiosk and was really impressed! It’s a brilliant resource that anyone can freely and easily use!

Super-dreadnoughts and a rare ship’s wheel!

What you see above is very rare. It’s a bronze and wood, 57 inch diameter ship’s wheel. It dates from the Age of Steel Riveted Hull and Steam, 1912 to 1930s. There’s photographic evidence that it might very well have been used in a navy’s super-dreadnought warship!

Joe Frangiosa was super excited to find this rare wheel. His amazing Nautical History Gallery and Museum inside Liberty Station’s Command Center building now features ship’s wheels from five different eras in maritime history. The huge wheel made its first appearance in his museum just a week ago!

Joe confided that this addition has been enormously satisfying. He installed the huge wheel in such a way that people can turn it and pretend to command the high seas. Kids love it!

Joe suggested you all visit his Instagram page here.

Check out my photos of the other four wheels. You might note that rope is tied around one spoke–the king spoke. When that bit of rope is located at the top of a wheel, that means the rudder of the ship is centered. A sailor can steer by feel in dark, stormy or foggy conditions.

The next wheel is made entirely of wood, with wood peg construction. It dates from the Age of Wooden Hull and Sail, 1775 to 1840.

The next wheel is made of iron. It dates from the Age of Wooden and Iron Hull, Sail and Steam, 1840 to 1887.

This next ship’s wheel is polished bronze and shines brightly! It dates from the Age of Steel Riveted Hull, Sail and Steam, 1887 to 1912.

Finally, this ship’s wheel without spokes is also bronze, but unpolished. It dates from the Age of Steel Welded Plate Hull, 1930s to 1945.

Advocates work for accessibility in Tijuana.

An important presentation was made this evening in San Diego’s Balboa Park. A thoughtful audience, assembled inside the World Design Capital’s Exchange Pavilion, learned how the organization Tijuana Access is working to make Tijuana and Mexico more accessible for the disabled.

Eduardo Lopez Ruiz explained how Tijuana Access is raising awareness and lobbying for greater accessibility south of the border. He explained that our neighbors to the south are a bit behind the United States when it comes to making buildings, streets and city facilities more friendly for those who have difficulty functioning in a world full of potential obstacles.

Working to make our world more accessible, Eduardo affirmed, is a matter of compassion. Not only are a significant number of people born with or develop a disability, but most of us become elderly–right?

There are all sorts of ways to make a city more accessible. Automatic doors, ramps, lifts, slip resistant materials and tactile paving can be adapted to enhance mobility. Handrails, rest furniture, properly placed buttons and switches, Braille printing and other changes can make life much easier and safer for many.

The presentation was mostly in Spanish with an interpreter helping us English speakers. I asked how I could link to Tijuana Access with my blog, because readers might like to help in some way. The Tijuana Access Instagram page is here. Their Facebook page is here.

To my readers in Mexico, perhaps this is a cause you’d like to support. Or simply spread the word to help to raise awareness!
