Jet planes meeting in the air to be refuelled, All these things I love so well. Chorus So I mustn’t forget. No, I mustn’t forget, To say a great big THANK YOU, I mustn’t forget. Clouds that look like familiar faces, And a winter’s moon with frosted rings. Smell of bacon as I fasten up my laces, And the song the milkman sings. 4 Chorus So I mustn’t forget. No, I mustn’t forget, To say a great big THANK YOU, I mustn’t forget. Whipped-up spray that is rainbow-scattered, And a swallow curving in the sky. Shoes so comfy though they’re worn out and they’re battered, And the taste of apple-pie. Choru. Air-to-air refueling can help rescue pilots coming out of dangerous regions or combat airspace. Refueling mid-air can extend the combat radius for pilots on more complex missions. The airplane engines must work harder when the plane is carrying heavy loads the same as with a car going up a hill. Flying with less fuel and refueling in the air is more energy efficient. It is estimated that air-to-air refueling saves 35 to 45 per cent in fuel costs.  With the usual air-to-air refueling, two airplanes must operate at a range of altitudes and speeds. One airplane must speed down or slow down to match the receiver’s refueling speed.  Are Private Jets More or Less Turbulent than Commercial Planes? The Top 6 Easiest Planes to Fly. About the Author.

Lifting your rocket from Terra's surface into circular orbit takes an unreasonably large amount of delta V. As a matter of fact, if your missions use Hohmann trajectories, the lift-off portion will take about the same delta V as does the Hohmann from Terra to the destination planet. As Heinlein put it:. Heinlein and I were discussing the perils of template stories: interconnected stories that together present a future history.

As readers may have suspected, many future histories begin with stories that weren't necessarily intended to fit together when they were written.

Unfortunately, in "Blowups Jet planes meeting in the air to be refuelled song on a capability for orbiting large payloads had been developed. If you can get a ship into orbit, you're halfway to the Moon. About 5. In other words it takes more delta V to travel the pathetic kilometers up to Low Terra Orbit as it does to travel the , kilometers to Mars! From Low Terra Orbit, where can you travel to with 7.

Oh, only to the Planet Saturn1,, kilometers towards jet planes meeting in the air to be refuelled song on edge of the entire solar system. Rob Davidoff suggests that in a rocketpunk future, people will no longer use the expression "worth its weight in gold. But the delta V cost breakdown is interesting. Getting into orbit takes just a little bit of delta V.

It is making sure you stay in space that takes a freaking lot of delta V. A little sounding rocket can easily rise from 50 to 1, kilometers above Terra's surface, where outer space starts about kilometers up.

Then the propellant runs out, and the poor little rocket finds itself unsupported hundreds of kilometers up. So it plummets to its doom. How do you support the sad little rocket? If it uses propellant it will eventually run out, sooner more than later. You can't build rocket legs that are hundreds of kilometers long.

You can't use a helicopter blade because there is no air. But what you can do is put the rocket in an "orbit". An orbit is a clever way to constantly fall but never hit the ground. The trouble is that entering an orbit takes a freaking lot of delta V, about 8 kilometers per second around Terra. Of course, once you have torchships you can stop all this child's play with wimpy Hohmann transfers and start doing some big muscular Brachistochrone trajectories.

Brachistochrones typically require delta Vs that are hundreds of times more than the equivalent Hohmann. So any ship that can handle a Brachistochrone is not going to even notice the delta V cost for lift-off. But even with torchships, the real bottle-neck restricting developing space resources jet planes meeting in the air to be refuelled song on the cost to boost payloads into Earth orbit. There are other ways besides rocket boosters and space shuttles to get payloads into orbit.

The traveling-public gripes at the lack of direct Earth-to-Moon service, but it takes three types of rocket ships and two space-station changes to make a fiddling quarter-million-mile jump for a good reason: Money. The Commerce Commission has set the charges for the present three-stage lift from here to the Moon at thirty dollars a pound.

Would direct service be cheaper? A ship designed to blast off from Earth, make an airless landing on the Moon, return and make an atmosphere landing, would be so cluttered up with heavy special equipment used only once in the trip that it could not show a profit at a thousand dollars a pound!

Imagine combining a ferry boat, a subway train, and an express elevator. So Trans-Lunar uses rockets braced for catapulting, and winged for landing on return to Earth to make the terrific lift from Earth to our satellite station Supra-New York.

The long middle lap, from there to where Space Terminal circles the Moon, calls for comfort-but no landing gear. The Flying Dutchman and the Philip Nolan never land; they were even assembled in space, and they resemble winged rockets like the Skysprite and the Firefly as little as a Pullman train resembles a parachute.

Accessing a km LEO orbit requires first the energy to get to km. None of these are realistic assumptions. This is very aggressive especially at sea levelwould probably melt the engine due to operating stoichiometrically, but it may actually be possible. The first stage weighs tons dry 25 times that wetand the next stage 10 tons dry etc.

Work: 3. We assume the dry mass magically can be recovered at no mass penalty I will address this in another post…. Or At A therm is about MJ. Such arguments are flawed. The two main types of orbit that launch vehicles boost payload into are equatorial orbits and polar orbits. Polar orbits pass over both the north and south poles, with an jet planes meeting in the air to be refuelled song on close to 90 degrees with respect jet planes meeting in the air to be refuelled song on the equator.

But the important point is a satellite in polar orbit will eventually pass over every single spot on Terra. Heinlein calls these "ball of yarn" orbits, since the path of the satellite resembles wrapping a strand of yarn around a yarn ball.

This is why such orbits are used for Earth-mapping, Earth-observation, some weather satellites … and reconnaissance satellites aka "spy" satellites. For communication satellites, space stations, resupply missions, space exploration, and pretty much everything else, you launch into equatorial orbits. When deciding where jet planes meeting in the air to be refuelled song on put a launch site, you have to plan around the Launch Corridor.

This is the path the rocket will take when launching which will [1] allow the rocket to reach the desired orbit and [2] if the rocket engines fail, the rocket or the remaining flaming rocket debris will only fall on uninhabited areas as long as it stays inside the launch corridor.

The standard practice is to arrange launch corridors to be over the ocean. Failing that, you need land areas where a rain of flaming rocket bits is unlikely to result in lawsuits or negative publicity.

And of jet planes meeting in the air to be refuelled song on ones that do not violate another nation's sovereign airspace. During launch, the range safety officer will be watching the rocket like a hawk.

If the rocket shows signs of leaving the launch corridor, the officer will hit the panic buttons. Unmanned rockets will shutdown their engines and vent their propellant. Manned rockets will have the on-board pilot take action, but if they are ineffective the range safety officer might have to shoot the rocket out of the sky.

Rockets launch due south so the launch corridor is thousands of miles of uninhabited Pacific ocean. The alternative is to launch due north, but that puts the launch corridor right across California, the long way. When you are dealing with feeble launch vehicles using chemical propulsion you need to use every trick you can find.

They have grotesque mass ratios which really cut into the payload mass. The most important trick is one to reduce the delta V the rocket needs to achieve orbit.

Since Terra is spinning on its axis, when the rocket is sitting on the ground it is actually already moving. At least it is moving relative to the desired orbit, which is the important thing. If you are standing in New York City; you, the ground, the skyscrapers, the taxi cabs, and everything else is moving at meters per second. The only reason everything seems stationary is because everything is moving together. Now remember that on Terra everything is moving due east because that is the direction Terra is spinning on its axis.

I gave you the entire equation in case you wanted to do the calculations for an extraterrestrial planet. If you are just trying to place launch sites on Terra, the equation is:.

The point is that the delta V the launch vehicle needs to achieve orbit is reduced by the tangential velocity of the launch site. Bottom line is the closer you can put the launch site to the equator, the better. That kind of delta V reduction can buy you lots of extra payload. Keep in mind that since Terra is spinning due east, the rocket has to launch in an easterly direction in order to take advantage of the bonus.

By the same token, if the stupid rocket launches westthe bonus turns into a liability. The important point is that on Terra the equatorial launch corridor is going to point due east.

The better science fiction novels put Terran equatorial launch sites as close to the equator as possible, and where an eastward launch corridor passes over lots of ocean i.

The New Guinea mountains, just south of the Equator and rising in places more than three miles above sea level, must once have been about the wildest and most inaccessible spots jet planes meeting in the air to be refuelled song on Earth.

Although the helicopter had made them as easy to reach as anywhere else, it was not until the twenty-first century that they became important as the world's main springboard to space. There are three good reasons for this. First of all, the fact that they are so near the Equator means that, because of the Earth's spin, they're moving from west to east at a thousand miles an hour. That's quite a useful start for a ship on its way out to space.

Their height means that all the denser layers of the atmosphere are below them, so that air resistance is reduced and the rockets can work more efficiently. And — perhaps most important of all — there's Jet Planes Meeting In The Air To Be Refuelled Song Name ten thousand miles of open Pacific stretching away from them to the east so if a rocket crashes there is no danger of it obliterating a town.

You can't launch spaceships from inhabited areas: apart from the danger if anything goes wrong, the unbelievable noise of an ascending ship would deafen everyone for miles around. Port Goddard is on a great plateau, levelled by atomic blasting, almost two and a half miles up. There is no way to reach it by land — everything comes in by air. It is the meeting place for ships of the atmosphere and ships of space.

When I first saw it from our approaching jet, it looked a tiny white rectangle among the mountains. Great valleys packed with tropical forests stretched as far as one could see. In some of those valleys, I was told, there are still savage tribes that no one has ever contacted.

I wonder what they think of the monsters that fly above their heads and fill the sky with their roaring… they are probably all deaf by now, I guess New Guinea is not classified as an "inhabited area".

But it isn't, the ISS is instead in a So that Russian cargo rockets from Baikonur Cosmodrome can reach it.
