This particular ufo I've seen twice in daylight, only I was on the ground. Same shape and moving just as fast....

The One,
Do you have that problem, too? Some let's you post and others not?

Is this the video in question?

This seems to be the same shape popping up around the globe. There are a good few of these filmed from Australia.

But I guess if people REALLY wanted to see it then they can go to YOUTUBE and look at it. It's called "UFO - Ovni Filmed from a Plane".
Thanks for the assist, The One. It wasn't just me having the problem....:thumb:

"UFO - Ovni Filmed from a Plane"
I feel like I've made a bigger deal out of this than it's worth.

If you look closely it seems that its flapping its wings.

Thanks Maia and The One ...looks convincing , but i wonder if some of these things are organic 'critters' like the rods ...Cheers Steve

High Bryn I did not think birds flew that high but apparently some swans do.....As most commercial jets cruise between 30,000ft-----39,000ft...


How Fast and High Do Birds Fly?

Generally birds follow the facetious advice often given to pilots -- "fly low and slow." Most cruise speeds are in the 20-to-30-mph range, with an eider duck having the fastest accurately clocked air speed of about 47 mph. During a chase, however, speeds increase; ducks, for example, can fly 60 mph or even faster, and it has been reported that a Peregrine Falcon can stoop at speeds of 200 mph (100 mph may be nearer the norm). Interestingly, there is little relationship between the size of a bird and how fast it flies. Both hummingbirds and geese can reach roughly the same maximum speeds.

There is, of course, a considerable difference between the speed at which a bird can fly and the speed at which it normally does fly. When the bird is "around home" one might expect it to do one of two things, minimize its energy use per unit time, that is, minimize its metabolic rate, or m e the distance it travels per unit of energy expended. A vulture loitering in the sky in search of prey might, like the pilot of an observation aircraft, maximize endurance; a seabird traveling to distant foraging grounds might, like a Concorde encountering headwinds on a transoceanic flight, maximize range. Staying up longest does not necessarily mean going farthest. A bird might be able to stay aloft 6 hours at 15 mph (maximum endurance, covering 90 miles) or 5 hours at 20 mph (maximum range, covering 100 miles). Birds can also choose to maximize speed, as when being chased by a predator or racing to defend a territory. Or they can choose some compromise between speed and range.

In order to determine what birds normally do, Gary Schnell and Jenna Hellack of the University of Oklahoma used Doppler radar, a device similar to that used by police to catch speeders, to measure the ground speeds of a dozen species of seabirds (gulls, terns, and a skimmer) near their colony. They also measured wind speeds with an anemometer, and used those measurements to estimate the airspeeds of the birds. (The wind speeds were generally measured closer to the ground than the birds were, which led to some errors of estimation, since friction with the surface slows air movements near the ground.)

Airspeeds were found to be mostly in the 10-to-40-mph range. The power requirements of each bird at each speed could be calculated, and that information was used to establish that the birds were generally compromising between maximizing their range and minimizing their metabolic rates with more emphasis on the former. Airspeeds varied a great deal, but near the minimum metabolic rate rather large changes in airspeed did not require dramatic rises in energy consumption. For example, a gull whose most efficient loiter airspeed was 22 mph could fly at anything between 15 and 28 mph without increasing its metabolic rate more than 15 percent.

Most birds fly below 500 feet except during migration. There is no reason to expend the energy to go higher -- and there may be dangers, such as exposure to higher winds or to the sharp vision of hawks. When migrating, however, birds often do climb to relatively great heights, possibly to avoid dehydration in the warmer air near the ground. Migrating birds in the Caribbean are mostly observed around 10,000 feet, although some are found half and some twice that high. Generally long-distance migrants seem to start out at about 5,000 feet and then progressively climb to around 20,000 feet. Just like jet aircraft, the optimum cruise altitude of migrants increases as their "fuel" is used up and their weight declines. Vultures sometimes rise over 10,000 feet in order to scan larger areas for food (and to watch the behavior of distant vultures for clues to the location of a feast). Perhaps the most impressive altitude record is that of a flock of Whooper Swans which was seen on radar arriving over Northern Ireland on migration and was visually identified by an airline pilot at 29,000 feet. Birds can fly at altitudes that would be impossible for bats, since bird lungs can extract a larger fraction of oxygen from the air than can mammal lungs.

Cidersomerset. Hi

Some go even higher.


The altitude record is held by a Rüppell's griffon Gyps rueppelli.

The altitude record is held by a Rüppell's griffon Gyps rueppelli, a vulture with a 10-foot wingspan. On November 29, 1975 one was sucked into a jet engine 37,900 feet above the Ivory Coast in West Africa. The plane was damaged but landed safely. What the bird was doing up so high I have no idea, since this species is not migratory.

The bird that flies highest most regularly is the bar-headed goose Anser indicus, which travels directly over the Himalayas en route between its nesting grounds in Tibet and winter quarters in India. They are sometimes seen flying well above the peak of Mt. Everest at 29,035 ft. Birds have some natural advantages for getting oxygen at high altitudes, in particular an arrangement of air sacs that allows them to circulate inhaled air twice through the lungs with each breath--much more efficient than the in-and-out system used by mammals. Bar-headed geese have special adaptations that make them even better at high-flying than other birds. They have a special type of hemoglobin that absorbs oxygen very quickly at high altitudes, and their capillaries penetrate especially deep within their muscles to transfer oxygen to the muscle fibers.

Other high flying birds include whooper swans, once observed by a pilot at 27,000 feet over the Atlantic between Iceland and Europe, and bar-tailed godwits (a shorebird), which have been seen at almost 20,000 feet. The record for North America is a mallard duck that collided with an airplane at 21,000 feet above Elko, Nevada in July, 1963. Most birds, though, fly lower--waterfowl typically at between 200-4,000 feet, and small songbirds at between 500-2,000 feet. However, the tiny Blackpoll warbler will fly up to 16,000 feet high in order to catch favorable winds on migration between Canada and South America. I'm not sure how well a sparrow would do, but similar-sized birds are quite capable of flying very high indeed.
