All my senses are being tortured simultaneously. It’s difficult to say what the worst part about sitting in 29E really is? Is it the stench of the sanitation fluid that’s blown all over my body every 60 seconds when the door opens? Is it the wooosh of the constant flushing? Or is it the passengers asses that seem to fit into my personal space like a pornographic jig-saw puzzle?

I learned about these arrows (and the early mail system in general) as a young cadet in Civil Air Patrol -- it was part of Chapter 1 of the Aerospace Education text that you had to read and pass a test on in order to earn your first promotion. Even back then, I wondered if any of them might still exist. At that time (1979), there was no way to even start looking into that possibility -- and, of course, it then fell off my radar. After I became a pilot, I occasionally wondered if I might happen to spot one someday, figuring that some of the VOR routes almost certainly follow some of the same airmail routes. I even entertained a dream of trying to retrace one of the coast-to-coast routes. After Google Earth came out, I started seeing about planning such a trip, but finding the needed information was tough -- it might be a lot easier now. I did, however, track down a few of the arrows. One of them is Arrow #5 near Las Vegas (the one he is standing on in that picture.).

Here's a Google Earth view of it:

The arrow is pointing almost due north (about 2° true). I don't know where it was actually pointing to (i.e., where the next beacon was). By coincidence, it is pointing right at what is now the Las Vegas strip and Harry Reid International Airport (8 nm from the arrow). At first, I thought it was pointing to whatever airfield eventually became Harry Reid, but that was Alamo Airfield, which was built in 1943.

Here's another one up near LoveLock, NV:

Old saying. Target the archer, not the arrows.
Back in the early 2000's I was at a conference and there happened to be a guy there that was in the Iraqi Republican Guard during Desert Storm, who had since managed to immigrate to the U.S.. I was talking to him at dinner one night and he told a story about the directions they were given by his sergeant (which didn't quite match the orders from higher up). At one point when they heard the distinctive drone of a C-130 nearby, they were told if they hear that during the day, they should shoot at it, but if they hear it at night, whatever else they do, do not shoot at it. When asked why not, the sergeant replied, "Because it's a gunship, and it will shoot back." Now, while that advice was very good as far as it went, it wasn't entirely accurate, because the AC-130 Specters were more than willing to operate and shoot back during the day, too. But, by and large, they were creatures of the night.

I remember a briefing a few days into the air war (I think from Riyad) in which the briefer was asked the state of the Iraqi Air Force. The reply was pretty memorable and went something like this: The Iraqi Air Force has the capacity to challenge us in the air during the day, and that is a situation that will continue for several more days. But by this point, Saddam Hussein should be under no illusions about one thing -- we... own... the night.

In the second mode, when the aircraft travels above Mach 7, the shock wave stops rotating and focuses on a circular platform at the engine's rear. This helps maintain the thrust through a nearly straight-line oblique detonation format. As the researchers describe in the paper, fuel auto-detonates as it reaches the rear platform due to the high speed of incoming air. The engine relies on detonation as its primary driving force throughout its operation.

British jets are reportedly gearing up to launch a series of air strikes against Iranian-backed Houthi rebels in the wake of recent attacks on shipping in the Red Sea.
Reports first published in The Times suggest that Britain plans to coordinate with Western allies, including the United States and possibly another European nation, to execute targeted missile strikes.

The potential targets include locations in the Red Sea or mainland Yemen, the base of the Houthi rebels.

The decision follows a warning from Grant Shapps, the UK Defence Secretary. On Sunday, Shapps stated, “If the Houthis continue to threaten lives and trade, we will be forced to take the necessary and appropriate action.”

The gravity of the situation is underscored by the planned release of an unprecedented joint statement by the UK and US, warning the Houthis against continued aggression towards commercial vessels.
I guess we will see if they get the message to stop attacking ships before the bombs drop.
It's likely there to collect signals intelligence on our drone and missile countermeasures if there is an offensive attack by us, not much of an attack threat (as a 55-year old Alvand-class frigate) on our forces.
