Jumbo jets travel at about 900 km/hr, and the moon is 384400 km from earth, so it would take about 18 days to get to the moon going that fast.\n\nHowever, jumbo jets work under the principles of lift propulsion, which requires air.  Since there is no air between the earth and the moon, the jet would be doomed shortly after takeoff.

It is the same footage because before it was leaked, now it has been officially released. This is what I heard here but I havn't been in the US since last november. Your link was the first i saw this footage leaked or released.\n\nCan't tell that it's a plane. My computers not great and it's a small viewing box but I guess enough have said it's not great where I believe that a larger view wouldn't help much. It also appears to come in horizontally only fueling my suspicion. I imagine a plane would come in at an angle, especially since the pentagon is not that high. Never flew a plane but flew enough simulators to know skimming across the ground that low ain't easy, especially for someone with little flight experience and probably never flew an actual jumbo jet before. Looks like a rocket fired sideways like in an explosion test. I can't tell it's even the pentagon. If they hoped to clear up rumors that doesn't help. They really did it anyway to remind us why we fight.

The simplest way to make a jet engine is to make or buy a pulse jet, which is similar to a ram jet, except it has a small flap or valve that sets up directional gas flow.  It requires a starting air flow from a compressor to achieve sustained operation.  The way it works is the air flows through the valve down a tube where there is some kind of fuel atomization, the fuel is ignited initially with a spark plug, the ignited gas make their way out the exhaust end of the tube.  The momentum of the gas leaving the exhaust at a rapid rate creates a vacuum for the intake valve to start the whole process over again.  Very simple and there are jets often sold on ebay exactly for model jet planes. \n\nAs for a turbine jet engine the only thought that comes to mind is a highspeed pencil router used for detailed engraving and polishing, that runs off an aircompressor.  These run at or around 100,000 rpm and two could likely be welded together very carefully to make a mini tubine engine.  Although this idea seems plausable, there will be major hurdels to overcome. Primarily balance is going to be the biggest problem,  when you have something rotating at 10's of thousands of rpms any non semetrical craftmanship would like result in a very short operational life.  Also I doubt that the bearings on the exaust side will not seize after the heat and particulate is sustained for a period of time.  \n\nTo this day I have never seen a turbine jet engine as small as you are asking.\n\nCheck out the following website for a pulse jet design.

*thinking a bit* Jet Planes are Airplanes that are propelled by Jet Engines, defined as...\nA jet engine is any engine that accelerates and discharges a fast moving jet of fluid to generate thrust in accordance with Newton's third law of motion. This broad definition of jet engines includes turbojets, turbofans, rockets and ramjets, but in common usage, the term generally refers to a gas turbine used to produce a jet of high speed exhaust gases for propulsive purposes.\n\nMost modern jet engines are actually turbofans, where the LP Compressor acts as a fan, supplying supercharged air to not only the engine core, but to a bypass duct. The bypass airflow either passes to a separate Cold Nozzle or mixes with LP Turbine exhaust gases, before expanding through a Mixed Flow Nozzle.\nForty years ago there was little difference between civil and military jet engines, apart from the use of afterburning in some (supersonic) applications. Turbofans today have a low specific thrust (net thrust/airflow) to keep jet noise to a minimum and to improve fuel efficiency.\n\nFor an excellent breakdown of the types of jet engines ect see http://en.wikipedia.org/wiki/Jet_engine#Types\n\nThe future of jet planes themselves seems on the civilian passenger side seem to be running along the lines of simply be getting bigger so more people can be transported at once.\n\nBut on the military end, Scramjets, or supersonic combustible ramjets are on the rise.\nIn its simplest form a turbojet consists of an air intake, compressor, combustor, turbine and nozzle. In a ramjet, owing to the high flight speed, the ram compression is sufficient to dispense with the need for a compressor and a turbine to drive it. So a ramjet is virtually a 'flying stovepipe', a very simple device comprising an air intake, combustor, and nozzle. Normally the only moving parts are those within the turbopump, which pumps the fuel to the combustor.\nScramjets, are similar to Ramjets, but the air goes through the entire engine at supersonic speeds, eliminating the strong normal shock wave in the intake. This increases the stagnation pressure recovered from the freestream and improves net thrust. Owing to the hypersonic (rather than supersonic) flight speeds experienced, scramjet air intake temperatures are too high for burning kerosene, so hydrogen is normally used as the fuel.\n\nThe designs of the planes are less rounded and are combining stealth technology with modern aerodynamics to create flatter, trianguler, higher thrust vehicles.\nIt's design minimises both radar and infrared signitures by using a combination of special materials, angles and shielded jet intakes/outlets.\n\nThe smoke that you refer to is actually condensed vapor called a contrail. Contrails form when hot humid air from jet exhaust mixes with environmental air of low vapor pressure and low temperature. The mixing is a result of turbulence generated by the engine exhaust. Cloud formation by a mixing process is similar to the cloud you see when you exhale and "see your breath".\nHow long a contrail remains intact, depends on the humidity structure and winds of the upper troposphere.\nhttp://cimss.ssec.wisc.edu/wxwise/class/contrail.html

1,000000,0000000 that is how fast sound really is.\n\nbut to answer you question just listen and watch a jet after the jet passes then it takes 15 seconds before you here the sound because the jet has broken through the sound barrier.

Earth is around, you know that. An aero plan has to fly around and it would be flying thousands of kilometers away from you.\n\n It would appear that the plane is flying so slowly. But if you see an aero plane that is flying on low altitude that would appear to be faster.\n\nSky is so wide, you can see larger area if you look further and further you can see more wide angle. \n\nIt is not same as if it is closer to you, the distance would be very small. If it is far distance is greater.

My favorite animal is the falcon. It can fly and is free. It is also really fast. And it is strong too. IT's also the official animal of the Us Air Force, which I am going to join.

A helicopter can hover, but in general an airplane stays aloft because of the flow of air across its wings-- so the answer is pretty much no. A Harrier jump jet can go straight up, but it really can't stand still for very long and expends a heck of a lot of energy doing it.

Ok, first of all the jet would stop working once you left atmosphere - but ignoring that for a moment and assuming you were in a craft capable of going 500mph:-\n\nWell at about 2.7 billion miles away, approximately 616 years.\n\n\n\n**update** Phew, so pleased to see that someone else concurred (+/-) 1 year, I suddenly thought I might have been out by a factor of 10 :)

You are using the term "power" incorrectly. Power is the rate of production of energy. A jet may have enough energy, but it does not have enough power. A fully fueled jet may be able to burn all it's fuel with oxygen from the surrounding atmosphere to generate enough energy to make it to orbit, but it takes many hours to do that, and all the time it is being slowed by friction with the atmosphere. The shuttle burns all it's fuel in 10 minutes, and it carries it's own oxygen in a tank so it can operate outside the atmosphere. So even though they may have similar energy, the shuttle has far more power.

Q:What would be the soonest fusion power could be operable in Europe if funding were increased, and energy funding diverted from fossil fuel energy research, and finally, if the fusion research projects of the USA, EU, and Japan were combined, what is the soonest fusion power could be efficiently operated?\nA: The next step from JET (and the other tokamak research being undertaken around the world) is a device called ITER, an international tokamak project, 2-3 times bigger than JET, costing several billion pounds and capable of producing significantly more fusion power for longer periods. This will demonstrate the feasibility of the plasma physics and fusion engineering of a potential power plant and, given the present funding, is planned to be built in the next 10-15 years - an eventual commercial power plant probably being 30-40 years away. However, if the present international funding for fusion were increased, ITER could definitely be built more quickly and fusion power could be a reality much more quickly - in possibly half the time if the present funding levels were increased significantly.\n\n \n \n \nQ: What developments in fusion technology are likely to take place in the future, say 10, 20 years from now? \nA: The next step device following on from JET (called ITER) is currently being designed and should be operational in 2020. This will demonstrate burning plasmas (with Q ~ 10 where Q is the ratio of the output fusion power and the input power required to keep the plasma going) whereas JET has achieved Q~0.6. It is then anticipated that a working, electricity producing reactor should be
