2021 Climate Change

Well you would not have to ask twice to get me in a F 16 or 35, thats for damn sure.
And i would not mind one fly over now and then, even break sound barrier, but living right in the landing or take off path, even for a Airport with Danish levels of activity, that got to be annoying.
My friend live not too far from the CIV / military ,Karup airport / Karup airbase and even if we dident see it, we was in agreement that we have heard a F35 ( probably German one visiting airports up here )
We just looked at each other and agreed "thats no F16 "

One time, I heard the weirdest sound I've ever heard from a jet aircraft coming up the valley and so I ran out onto my deck to see what it was. I saw a strange looking black jet aircraft approaching low and slow and it passed overhead so low that I could literally see the rivets and other details on the damned thing. It was an eerily sinister looking aircraft. Suddenly, I realized that I was looking at an F-117 Nighthawk stealth fighter and recalled reading in the local newspaper that there was going to be an airshow in nearby New Hampshire that weekend that featured the stealth fighter as one of the star attractions. Apparently, as it was Monday, the craft was now leisurely returning to base. It was an amazing sight to see and because I live on a small mountain I got quite a look at it!

Best, most "eerie sounding" aircraft at our local airshow a few years ago, unfortunately no longer flying, seen with my old house in the background:

Speaking of louder and louder, I recall visiting the site of a mountain ridgeline wind farm here in Vermont and witnessing first hand what they sound like when standing perhaps 150 -200 feet away from the closest turbine. Each turn of the blades made a loud whooshing thump with a pressure wave that you could feel in your body. And these were relatively modest sized turbines by today's standards. I can't imagine the sound and pressure waves generated by these massive turbines. Of course, that is why they site them way out in the ocean but it seems highly likely that they will affect wildlife above and below the ocean surface.

The noisiest I've heard here was one of the smallest, really unpleasant noise, the big ones are normally the quietest, only time I've heard a thumping noise is while they are adjusting to a new wind direction, then they go back to just wind noise with a slight whoosh if you are closer than about 200 ft.

Normally it is hard to hear them above the noise of the wind!:

 

[Nigel]

There are lounder and louder voices when 5 - 6 smaller turbines in the field "behind" the house are to be replaced with 3 mega turbines.

Why bother with 3MW onshore turbines when you could replace 9 of them, or 54 of those smaller ones, by just one 27MW offshore and get more reliable power!

At one point, it almost sounds like something is horribly wrong with that airplane! Some of it appears to be the acoustics of the location as the aircraft makes the turn and perhaps a change in the throttle. Aircraft design has certainly evolved since 1956 when the Vulcan was first put in service.

I wish I could describe what the stealth fighter sounded like. Perhaps if I have time later I can find a video that might do it justice. What I recall was that it was such a unique sound compared to any other aircraft I'd ever heard fly over my location that I dropped what I was doing and ran outside to have a look.

The Vulcan is famous for its howls, apparently a resonance in the air intakes which like your later stealth bombers are designed to hide the engines from radar, but which were designed back in 1946 before computer airflow modeling, so they got it less than perfect, then decided to leave it since it was only supposed to be a deterrent, and anyone hearing it would be more likely to avoid being attacked! Seems to only be audible from certain directions, but it wasn't echoing back in this case, it was filmed from an open field, that is what it sounds like at certain throttle settings given certain atmospheric conditions.

It is also known for making car alarm sounds:

Amazing takeoff for a bomber, ending in a more normal howl not heard from the best direction:

The vulcan is a damn sexy plane, and also one of the louder ones i believe

 

[Dashmellow]

Interesting. Kamkar's right, it sure is a noisy airplane. It looks oddly graceful and ungainly at the same time, such as on the unusual takeoff, but as you point out, it is a bomber. A cool airplane, nonetheless!

 

[kamkar]

Sadly the vulcans had a tendency to loose nukes here and there 😉 not things you want to loose.

 

[Nigel]

now and again and we also get F-15s from the Massachusetts Air National Guard’s 104th Fighter Wing flying over my location.

I had three of your F-15s over me the other day, including the new Eagle II, but they stayed so high I couldn't see them.
Trouble was that high meant I could hear them continuously until they ran out of fuel!

I was in the middle:

It is amazing how often nukes have been lost by various nations.

It is easy to forget its size, not the little fighter that it sometimes appears to be when doing aerobatics:

 

[kamkar]

Well the English lost the whole plant too, damn near 007 did not find it

Still don't know how they managed to land it intact in water, it was designed to outperform fighter aircraft at 60,000 ft high, not subsea!

Only time one was ever taken out was when we nuked the USA, but since we had more than one it was still successful:

Yes, it is a bomber of course.

dident that make them angry, we are their best friends and still they did a Banzai run on us with a B52 loaded with hydrogen bombs, fortunately way up in Greenland.

The idea of the exercise was to find holes in the USA defences, which we did, they then fixed them and invited us back the next year.

Unfortunately they fixed them by adding an extra 1000 expensive interceptors but failed to fix the problem, which was that the Vulcan was a stealth aircraft and by the time their radar had detected it, it was too late to launch the interceptors and get them to 60,000 ft, and even if they did get up there, the Vulcan was more maneuverable than they were at that height due to the huge wing area. So then they got angry and for the 3rd exercise they changed the rules - no Vulcans! So IIRC we flew a little wooden Swordfish biplane into the centre of New York at 50ft, completely undetected by their radar! They didn't learn the lesson though, 9-11 still happened.

They weren't quite so happy when we intercepted their U2, the world's highest flying aircraft, from 22,000 ft higher!

Diamonds are now a waste product of hydrogen production, so will they sell the hydrogen and give the diamonds away, or give the hydrogen away and sell the diamonds?

‘We will make zero-CO2 hydrogen from natural gas so cheaply we could give it away for free’

US start-up H Quest says its emissions-free microwave plasma pyrolysis technology will turn methane into H2 and high-value solid carbon or petrochemicals — with these “co-products” alone making projects profitable, writes Leigh Collins

Obviously the diamond market will become saturated long before people have enough hydrogen, so they need to be selling the hydrogen!

But the process still uses a lot of electricity, so better to use wind turbines for hydrogen production than continue mining fossil fuels!

A tallyho may have been uttered on the airplane radio 🙂
I was not aware we still had F104 in the early 80ties.
