First @acarsdrama feed from New Zealand came online tonight!
We are now at 290 feeds from 25 different countries.
All continents are represented, except the uninhabited ones.
Super cool.

Something is off with this (aside from the black tank) USMC F/A-18C's 164731 of VX-31 "Dust Devils" on final Pt. Mugu, during Grey Flag, September 2025. Post responses in comments #FA18C #GreyFlag #photography #aircraft #VX31 #DustDevils #aircraft #nasptmugu #Nikon #Z9 #avgeek #photography #cvvhrn

@whatifbot that’s just a Jeroplane

The glider now has 12 pounds of lead shot and epoxy added to dead space in the very end of the tail boom.
My initial estimate of volume indicated that I could add 8 - 10 pounds this way. I'm pleasantly surprised, and I didn't make a chocolate covered mess of things as I was pouring this goop into the tail.
I need to add a few more pounds to the tail. Phase two of this project will use lead plate, bolted to the vertical fin spar. (I need to unroll the 1/4-inch plate first, then develop a template to cut the lead.)
I could not add the epoxy/lead shot mix all at once because of the exothermic reaction of epoxy. When mixed epoxy is in a thick blob (instead of a thin layer), it generates enough heat to warm itself...which accelerates the chemical reaction...releasing more heat...further accelerating the reaction.... I have seen epoxy smoking hot because of this, so I added a bit, waited a half hour, checked temperature with an IR non-contact thermometer, added a bit more when it was clear that the exotherm was only very mild, etc. That took a while, but turned out well.
I note that Roto Metals has a discount on some 1-inch lead plate. Get your fork lift ready. No free shipping!

Where is the center of gravity of the empty glider located?
If you measure the location of the main wheel and tail wheel (reference to something such as the glider's nose), and the weight each of them carry...you can do the math to answer that question.
Where is the center of gravity when the pilot is in the glider?
Climb in, and then take the same measurements.
Now I know if I need to add trim weights to the nose or tail, and how much.
Determining center of gravity location is critical for safety of flight and good handling characteristics. I'll do these measurements and math more than once so I can be very confident of the results.

Garmin “Autoland” aka “Safe Return,” has been used for the first time, successfully.
Autoland is an emergency system, where a passenger can hit a big red button if the pilot is in incapacitated, which causes the airplane to make emergency radio calls, navigate to a nearby airport with a long runway and medical facilities, and conduct an instrument approach and landing, followed by a full shutdown when the aircraft comes to a stop on the runway. Large screens and voice announcements keep passengers updated along the way.
The nature of the medical emergency on Saturday, involving a King Air with an unconscious pilot, has not been disclosed.
