What kind of hyperdrives exist on a puddle jumper?

[OsirisDICK]

If the Ancients were so far advanced, why hasn't anyone from Atlantis simply tried to fly a PJ back to earth?

Well, PJ's are made to go through the Gate. They don't seem to have a hypedrive at all.

yeah we have seen pretty much all of the inside of the puddle jumper and the only engines are the ones that retract and those are just standard engines.

[corey2002]

there are'nt any-

Spoiler:

we learn that in The Defiant One

IMO it exists a critical size to build a hyperspace-travel ship.
Since the beginning of SG-1, we havent seen any ship able of efficient hyperspace travel under the Teltak size (approxymately 3x more big than a PJ)....

Spoiler:

There was the Anubis escape pod in Homecoming, but it s an escape pod... I mean, not a vessel with long-time life support.

More, gateshipping is more economic and faster than hyperespace travel, for little exploration jumpers...
Ancients may have reserved hyperdrive for transports, cargo ships etc.

Jumpers were meant to go through the gate. End of story. I mean, they were the ancients. I'm sure they had a few other classes of vessel, including a cargo ship sized ship.

Spoiler:

In "Before I sleep" we learn that the Ancients in Pegasus had other ships with hyperdrives, but they were all destroyed by the Wraith during the seige on Atlantis.

[Dreadnought]

Yeh im sure the ancients had many other types of vessel.... hell, even Atlantis is a vessel basically

We know of the following vessels the ancients had:

Spoilers...

Atlantis
Puddle Jumpers
Warships - Which were superior to wraiths 1v1(Before I Sleep)

Spoiler:

Did they explicitly say that all of them were destroyed? I know several were, but I don't remember them saying all.

Anyway, I'm pretty sure the Jumpers have two engine systems. One is, of course, the drive pods, which can go in and out. These are designed for higher-speed travel. The second system is located on the bottom of the jumper, it looks like a strip of glowing-ness. It's meant for takeoff/landing, and of course Gate travel. From what I've noticed it's only glowing when the drive pods are retracted, so it makes sense to me.

That makes sense actually.
Spoiler space-38 minutes






What always bothered me about 38 minutes was when it's said the Jumper went through the gate on inertia, implying the engine pods were the only form of propulsion, so it always bothered me that, when it's going through the Atlantis gate, from taking off to entering the engine pods are retracted; so how is it moving?
But if the glowing strip thingy is some sort of anti-gravity thing it could work; on a planet it works since there's a planet-worth of mass to work against, but in space there's nothing.

[aAnubiSs]

There's always gravity

Probably.

I mean, it makes sense, Just pick up some speed and go through the gate. Naturally, that would only work in space. Less wear and tear on the engines.

Also, the cockpit was through the event horizon, so there was no way to tell it to go forward.

To the original poster: the name "Puddle Jumper" is significant. A puddle jumper is a small utility airplane used for moving passengers and cargo over shorter distances, usually in remote areas. For example, my uncle lives on a large island off the coast of Alaska, and there is an eight passeneger plane that makes several trips between the island and the mainland every day.

In Atlantis, the Puddle Jumpers exist to service places accessible through the Stargate. Their just small utility craft. For tasks involving hyperspace travel, the Ancients would have had other, purpose built ships (warships, transports, etc.)

Anubis' battlebarge was huge, we see a hat'ak under it at one point and it was a little bigger than the center of the whole BB, which is what the pod was, so it was likely alot bigger then even an Alkesh.

What I'm wondering is why there aren't any blueprints for building ships around atlantis. Surely the atlanteans would have saved and safeguarded that information somewhere in the city?

The team really needs to get cracking on building ships...they should have been this whole time if you ask me. Plus, that would be one of the best ways to learn about the atlantean technology.
