I don`t know what they`re called or what type of plane they are, but Australian bushfire-fighting planes scoop water up as they fly low over a lake, air pressure sucks it in somehow. I`ve seen it in real life and its just magical the way the water seems to leap into them. So no, not all planes have to return to base to reload.
Actually, we need both because each has advantages over the other. Fixed-wing tankers can carry more water on average, but they can`t fly as slowly or maneuver as well, so they can`t deliver it as accurately as a chopper. Also, fixed-wing tankers must return to an airfield to refill. A fully loaded 747 needs a 10,000` runway to take off, and the nearest one of those might be hundreds of miles from the fire.
Helicopters, on the other hand, can refill by lowering a siphon hose or a bucket into a small lake near the fire. So while each load is smaller than the tanker`s, it can make several drops before it needs to refuel, and that can be done from a tanker truck parked near the fire. The down side to choppers is that they are MUCH more expensive to purchase and operate, and fewer pilots can fly them.
We need these for more wildfires. They`d be better than the the comparable teeny helicopters that do it...
Planes are NOT emptied in mid flight. Poses a saftey risk.
This video shows a supertanker for forest fires. It was a plane converted to hold water. They were doing a demonstration in this video.
this is obviously for wildfires.
Theres a link to a video that explains exactly what this plane is AT THE END OF THIS VIDEO!
It is a super tanker and has been converted by Evergreen International. Hell they even have a website about it:
Septic Tank my ass
It`s "PPS". Post-Script means "after the writing", therefore another comment is a "Post-Post-Script", not a "Post-Script-Script".
You`re doing it all wrong :-)

OldOllie was right. The plane IS a tanker. Check out..... http://www.avweb.com/avwebflash/leadnews... . These planes are made to be used as water bombers for forest fires, and they are called the Evergreen "Supertankers".
P.S. Before trying to spout out that you are a know-it-all and someone is wrong, be sure to do some research so that what you are talking about is really correct. Just a thought.....
P.S.S. The link I posted contains a picture of the same plane that is in the video.
oh sorry excuse me.
Nope, it is a commercial 747. You can see the windows in the blue strip if you look closely. It is alot of water, but what you are seeing is a mixture of several things all happening at once. Firstly, if you spill a cup of milk, it looks like alot, but its only a cup of milk. Same thing, but with the altitude the water expands as it freezes (check this out http://www.youtube.com/watch?v=a8Hy1Pxyk...
Have you ever walked down the street and had a freak 10 second downpour? Oh poo.
Also, it is a well known fact that urine dropped at a high altitude will always form into the shape of a javilin. Something to do with the yellow food dye in pee or something like that.
