Flying Triangles

I don't see why that mistake should be surprising. Flying a plane is a practical skill, not a theoretical one. You need a minimum level of "intelligence" to learn, but you certainly don't need even a high-school level of physics education.

If taking off from conveyor belts ever becomes a standard flying technique, pilot training will teach what needs to be known about it. Until then, it's no more relevant to a fixed-wing pilot than knowing now to control a helicopter in hover.
No. There's something wrong with a pilot who doesn't realize forward thrust is coming from the prop and not the tires.

Do you have the link to this episode of Mythbusters?

The plane flies because air is flowing around the wings. What was this video suppose to demonstrate?

So the video demonstrates that dumb people can fly planes too? Therefore it follows logically that if a pilot observed a UFO, he must be dumb? That doesn't seem like a very strong argument. I think that the individual pilot who saw the UFO would have to be tested for "dumbness".

I just thought of a sure fire way a pilot can get evidence that the UFO he/she is observing is real. If the UFO gets too close to the plane, the pilot should deliberately crash into it. If it's just a weather pattern, the plane will fly right through it. If it's not, then an FAA investigation will reveal that the plane collided with something.

A great plan except for cases when it's actually something real, such as as another plane.

It demonstrates that thrust comes from the propeller and not the wheels. The surface on which that plane is sitting is being pulled in the reverse direction of take-off by a guy in a truck. Sone people think that would render the plane unable to take off. There were endless internet debates about this.

What follows logically is that you can't necessarily ascribe all kinds of expertise to people just because they're doing "what they do".

That pilot would deserve a Darwin Award for trying, anyway.

But the Belgian airforce locked onto triangles that they found in their air space. Within 5 seconds, the triangles were observed to break lock by accelerating rapidly. You can't get gliders to do that. The argument could be made that these triangles are secret (under research) US military planes. Military planes can detect radar lock and respond accordingly.
The Belgian event is interesting because it involved the military and went public almost immediately. One explanation that seems possible is that we [the US] were toying with our allies and projecting false RADAR images from a nearby Stealth Fighter [or by some other means]. The photos and reports of crafts seen in the area fit the profile for a Stealth, right down to the red light on the bottom. Also, the object seen on RADAR and chased was never observed visually. And it appeared to dive below ground level for a short time.

We now know that we transmitted false RADAR data in the first Gulf war, so the technology has been around for quite some time. As a matter of fact, I once proposed this technology in a physics class as a way avoid speeding tickets.

I want to assume that those who witnessed the event were sincere about what they observed or thought they observed. In other words, let's assume it's not a conspiracy. For the Belgium event, there were:
1. hovering triangles: explained as handgliders with spotlights;
2. scrambled jets and ground radar mistaking weather patters for triangles but not visually observing them. or,
3. scrambled jets observing a secret US made triangular shaped stealth fighter plane with three spot lights and high maneuverability.

I think #3 makes a little bit more sense without being "out of this world". Handgliders and incompetent pilots and radar technicians just seems a bit of a stretch.

Why you would think that "secret military project" is a more reasonable explanation than mistaken pilot, radar technician or media hyperbole is beyond me.

Many years ago I worked on the B2 program, and I was often the first person in the "white world" to hear when a plane landed from a test flight. One time I had a conversation with the caller about how the UFO sightings would go through the roof during flights. If false radar is involved, I am 100% certain that this would explain the sightings and Belgian air force event. But then again, I am one of those boring people that believes all UFOs are of terrestrial origin.

They are, but their propulsion system is derived from the plans for Tesla's Death Ray, which was stolen from his apartment on the day he died by agents of the Government and which technology is now a CIA black ops concern. They also have silent black helicopters that kidnap and mutilate cattle.

The military pilots never directly observed the target. The photos and reports of observed crafts were public, not military.

As for mistaken RADAR hits, RADAR mirages and the like, these explanation do not seem to be consistent with a plane in pursuit and changing direction. Any weather phenomenon or mirage would be good for one or a few hits. At the least it would have to be a failure of the RADAR system.

Thrust doesn't make a plane take off. Lift does.

OK, so the pilot may have made an order-of-magnitude error estimating the ground effect of the conveyor belt on lift. But I would be a lot more worried flying with a pilot who didn't know that ground effect was important, than somebody who made that mistake.

This does not change what zooby said.

The thrust (which will move the plane, which will provide lift) comes from the prop. What the wheels are doing under the plane does not affect thrust or lift. It is troubling that a pilot would make such a mistake.

Oh come on. Ground effects are helpful but incidental. Thrust gets the plane moving forward, which gets air flowing around the wings which creates lift. If ground effects were required, jets couldn't take off, and prop planes couldn't fly above a very low altitude, nor could you launch a model glider with your hand.
