"Fake News" ? ? ? Whatever happened to good old fashioned logic and good sense?

I saw a video where an airplane lost a wing during stunt flying and the pilot managed to safely land the plane. Yes - that's absolute bogus bologna.
Are you making that assertion based on a belief that no airplane could possibly fly and land safely after losing a wing?

I remember this:
F-15 landing with one wing gone.

While I was in Vietnam we (Marine Air) were flying the F-4 Phantom, A-6 Intruder and Prowler and the little A-4 Skyhawk. The little A-4 was a remarkable little single engine jet. I saw more than one return to DaNang missing large sections of wing as a result of SAM (Surface to Air Missile) damage. However, the Israeli F-15 takes the cake, I still can't believe the thing flew.

Saw an A-10 come back pretty badly shot up but still landed. Most of the left wing was gone (think it was left). MOST of the wing gone. In the video I posted, this guy looses the wing right up to the fuselage. Not everything you see on the internet is factual. In fact, this video has been debunked. Let me see if I can find that one too.

I was going to agree until I watched it. It's a pretty good job of a fake, if it is. If it's fake, then did the plane actually lose a wing and then crash, or is the whole thing fake?

@wayneh Fake. Actually I know nothing about the plane, the video or the circumstances, but it just can't be real. An intact wing's job is to provide lift. There's no way you can get a wing to drop like this one does upon landing. A plane in such a circumstance would cartwheel down the runway or grassy field, provided the pilot COULD manage to get it into what's called a knife's edge maneuver.

But what this has to do with solar? Well, I suppose you could look at shadows and compare. But solar energy is the topic. That and somewhat devolved into storage systems as well.

Not saying that everything you see on the Internet is factual -- I'd estimate that the larger fraction, by far, is not. I just asked about your basis for calling BS on that particular claim. Was it specific to THAT claim, or was it a general assertion that, sight unseen, it must be impossible? I know the video you are talking about and, yes, it was a hoax and shown to be a hoax years ago. But if the claim that it was a hoax was based only on an assertion that it must be a hoax since no plane can possibly fly on one wing, then the fact that you called it correctly is only coincidence, since the F-15 has demonstrated that it CAN fly and land with an entire wind ripped off right up to the wing root (and, even worse, with the remnants sticking up into the airstream). But, because of the amazing control authority of the horizontal stabs on that aircraft, it was able to remain aloft.

Put another way, do you maintain that the claim that that Israeli F-15 landed with one wing missing is a hoax?

BTW, the footage in the documentary posted by Reloadron ARE fake -- there was is no footage of the actual event, so they photoshopped out the wing for the documentary. But the still photos are genuine.

You really need to understand that United States MARINES are able to do a whole lot of things that nobody else could ever do. "No brag, just fact." Research will verify this, or you can ask any recruiter.

My point is to the web that not everything you see is factual. I sited the stunt plane as an example of a hoax. Same can be said of the myriads of over-unity machines. My BS call was on that particular video. As for an F-15, I find it hard to believe. Can't call BS one way or the other on that claim as I was neither there to witness it nor have I seen any real evidence that an F-15 can do as you claim. Not saying it can't; just saying I haven't seen ANY evidence either way.

My assertion was a general assertion, I did not see it live first hand either. And after seeing the SF in so many movies it is clear that anything can be faked. Recall that Japanese anti-gravity car video from a while back??

After watching the video on the F-15 posted back in post # 122 and listening to the pilot at his interview, the F-15 "has a wide body which at high enough speeds - you don't need wings." Yes, I agree. NASA has experimented with "Lifting Bodies", crafts that fly without wings and yet is navigable via surface control. So I don't doubt the claim of the F-15. I would have liked to have witnessed it myself, but I can't be everywhere. Not yet anyways.

Haven't seen the anti-gravity car from Japan yet.

Having been a USMC recruiter I can attest to that. Like the Internet I wouldn't say it if it wasn't true. Trust me on this. :)

Hey, are we going to get back to solar power? I was just wondering.

Ah yes - Solar panels. Would need a set facing to the south at a 30˚ angle to collect winter sun and a westerly facing set at around 20˚ to collect late afternoon sun when most people are coming home and running the AC and the nightly news on plane crashes.

I have always wondered about the relative cost effectiveness of fixed panels versus movable ones. And I have been amazed at those who tout having a servo move the panels instead of just a regular motor drive. For a given location, the sun's position at any time of the day is fairly predictable. It varies a bit with the seasons, but again, that is also fairly predictable. So why spend money and effort for a servo?

I have a telescope with a mount, can't think of the term for it but it aligns with the poles. Then a motor merely slews the scope across the ecliptic plane and will accurately follow any object in the sky that I point it at. You can do that with a panel. As for the final tilt of the panel, up 27 degrees or down 27 degreed, or somewhere in-between, depending on the time of the year and you have a panel that follows the sun, just like the Beatles.

[edit] Equatorial mount.

I was thinking of making a solar tracker for a couple of panels on my shed. It would not be a sensor, but a system to drive the panels to a calculated point as the sun's position is known. That way it is immune to dirty sensor or similar problems. Spiders crawling over the sensor spring to mind! An old car front wheel bearing assembly was what I want to use as it has the strength and availability. But I probably will not get around to doing that.
My shed solar is just 24V and it runs my soldering exhaust fans and the ham radio. The plan was for it to also run my whole home network and telephone system as they are on 24/7. But once again, I may not get to do that either. I'm slowing down as old age catches up ;)

One thing I'm hoping to do in a few years with my daughter is a solar panel with a tracker. This would let me introduce her to some electronics and also some interesting math in a context that is clearly relevant. Ideally, I'd like to set up some comparisons between fixed position panels and various tracking methods and take data so that she can evaluate the pros and cons. I think it might make an interesting science fair type of project. The trick is to get her interested.

Science fair: My son wanted to build something that could detect different colors. Junior high school. A bit over his head. Heck! A bit over MY head. So instead I coached him to build a light meter with an audible tone. The more reflected light the higher the tone. That way he could prove the reflectivity of different objects and materials. Then we mounted the whole thing in a deodorant container with a few switches on the bottom and the photo-resistor on the top. He got an A but didn't win anything. Some kid built a box in keeping with a recent fire prevention class everyone had to attend. His project was you would touch a question with a probe and with another probe - touch an answer. If you got the right answer you got a bell. Wrong answers got a buzzer. The whole thing was in a shoebox. Pretty good project. And in keeping with the classwork. I never did figure out how he wired it.
