NO Air

hey guys whats up i just bought my gun package and i got the 9oz tank when i screwed it in and i added a few painsballs in to shoot i couldnt shoot nothing noballs came out like there was no CO2 in the tank, these tanks when u buy them with the package are they empy and do u have to fill them up, cuz it seems to me the tank is empty, and i got the 98 custom and i also acidently pust the rear aim adjuster off and i was wondering if that would be a problem and if it would be easy to re attach

GI is right tanks are shipped empty. Its i believe illegal to ship a full tank.

Not only that...but inside of a hot semi-trailer...all the burst disks would blow.

Baggage compartments arent I believe

No, the oxygen tanks used in high altitude aircraft are EXACTLY the same as the HPA paintball tank...Kevlar, carbon fiber or fiberglass and all.

A tank that holds 5000 psi inside is not affected by lower pressure on the outside. Atmospheric pressure pushing on the outside of the tank at ground level is only 15 psi...even taking the paintball tank into the vacuum of space would have no impact on its ability to safely contain the 5000 psi air inside.

When an aircraft is pressurized for example 35000ft , only 8psi is needed to maintain the cabin pressure at a comfortable level.

The subject of transporting pressureized containers is covered in your HAZMAT handbook.  If you don't have one please stick to what you know. 

hey guys the neww FFA Regulations state that all preassure vessels can be boarded, but the pinvalves and regs. must be removed. that is why the new hpa bottles have longer thread necks and use no locktite when installed. an empty tank the reg comes out very easy

They can be used as bombs if carried on.

Uh, where do I begin. Lets see, Middle School science class or, hmmm, maybe High School physics class.

A tire explodes because its structure is designed to hold a specified level of pressure. If you pressurize it to its maximum rating then hit a pot hole or it is degraded in strength because it has been exposed to UV for a year or there was a fold in the tube. Just like a balloon, the tube has a physical size limit. If the lowering of external pressure causes the tube to grow larger than its design physical limity it will fail. A tank designes for thousands of psi, 15 lbs of differential has no impact on its structure.

It is against FAA regs to transport pressurized cylinders because:

1. A cylinder that leaks or ruptures its safety disk  in an enclosed area (cabin of a plane) may displace the oxygen. (CO2 Cylinder!) Causing asphyxiation.

2. A cylinder may have a defect that could cause it to rupture. Such an explosion in the confines of an aircraft (having nothing to do with the fact that it is in an aircraft) could bring it down.

All the possible dangers of high pressure cylinders that might cause injury or damage on the ground become critical problems in aircraft due to damage, depressurization, or close proximity of passengers.

It simplifies things just to not allow them in any state of fill or containing any gas...allow them on board only if verifiable empty.

And again, atmospheric pressure squeezing the tank at  sea level is only 14.7 psi. The tank can contain thousands of psi. It makes no difference what the outside pressure in  wherever the tank is...at sea level or in the vacuum of space. Oh, BTW if your bicycle tire were in good condition and mounted correctly on the rim, it could be taken into the vacuum of space with no problem (there are some considerations due to the physical structure and maximum internal pressure...but of no consequence in this level of discussion)
