Fun fact: the dumping speed has to be carefully calculated as to not reduce the aircrafts weight too much too quickly. If it dumped too much water too fast the plane will “bounce” in the air and it can actually rip the wings off, or cause other non-catastrophic damage to the fuselage. A fire fighting c130 ripped off both of its wings many years ago partly due to fatigue cracks in the wing attachment points, which grew large due to the rapid reduction in weight when dumping.
It's not an issue of "reducing weight too quickly" ... it's that the aircraft needs to remain within its center of gravity (CG) envelope while doing it. As far as having compromised wing spars - that's a whole other issue.

@@elijaha773 Don't do it when there's extreme fire danger and all the firebombers are busy doing real work, obviously. Likewise don't have an airshow during a pandemic. There have been, and I hope will be again, times less desperate than these. It would basically be a medium to large bonfire, something that isn't uncommon nor dangerous if done with proper precautions. Something that could easily be handled by ground-based fire crews if the fire bomber doesn't succeed in putting it out, and will be prepared in such a way that the fire would be contained and wouldn't spread to anywhere it could do damage.
They must have anti-sloshing baffles or something like it in there like rockets have. All that weight knocking all over the place is enough to bring even a craft as powerful as a 747 down.
They may have baffles like in fuel tanks, but they generally fill the tanks entirely so the water or retardant doesn't have room to slosh around. It is carefully balanced around the center of gravity such that even while it is emptied there is minimal change in the CoG.
Though I am currently flying B737-8NG, but I still admire this beautiful, excellently design aeroplane. I used to call it a humble giant whenever I entered its cockpit.
its definitely a design consideration for the avionics, since they would have to have systems that do the same thing but with fuel if you think about it
I know practically nothing about aircraft, but how do they keep one of these on level flight when they suddenly drop all that water out of her. Does the centre of gravity shift when they drop the load?
Odds are they have multiple tanks that are used, and they just adjust the speed of the pumps to keep the center of gravity the same. I wanna say its exactly the same as what the fuel plane does when refueling fighter jets
As long as the tanks are symmetrical to the Center of Gravity the pitch should not change. The only thing that changes is that the aircraft would start to climb, because the gravitational force becomes lower than the lifting force generated by the wings. And I assume to counteract this effect they re-trim the aircraft. Correct me if im wrong, thats just my educated guess
Looking at this makes me feel bad for the places that have drought and water shortage..but then again this is also to save lives. Just so much water for testing.
I just saw this aircraft in Anchorage Alaska now owned by National Airlines and reconfigured as a freighter. At least its still in the super tanker paint livery. Its terrible the forest service canceled its contracts and then we had such a terrible fire season this past summer and fall
I think that I would be more efficient if two tanker aircraft pass almost together, because the first drop don´t attack too much over the fire but if you drop water almost inmediatelly of the first one, the second drop of water will have more impact over the fire. Maybe the first tanker could be a little aircraft such as C130 and then as second tanker the B747.

The captain just turn on the fasten seatbelt sign and then the water stays put pretty well.

that's a lot of water to dump on the flight line. how long does it take to fill and how much is the bill?
Does the system compensate for loss of all that water weight or is It done manually by the pilot to keep level flight?
that is good question. And presure or will implose.
Manually, these pilots are madlads

Such a beautiful plane. Thanks for sharing, that was much higher pressure than I imagined.

Well your getting lighter so you probably go up in altitude a bit while speeding up
I'm curious to know for such a short time frame on the drop, how long does it take to land, refill, and take off again?

All jokes aside, that is straight up very interesting. I wonder if the pilots can feel if the aircraft gets lighter as it releases all that wright
How much of the fuselage is used for water storage tank{s}? How many drops can they make on each flight before having to refill?
Show the result maybe after dropping it, how much really arrives at the ground ?
Pilot: we have some engine fire...
Tower: okay, we set off an emergency and put on the runway!
Pilot: That's okay, we do it ourselfs :)
Well, guys but, is this a procedure, to drop the remaining water or was it done for this video?
I think that I would be more efficient if two tanker aircraft pass almost together, because the first drop don´t attack too much over the fire but if you drop water almost inmediatelly of the first one, the second drop of water will have more impact over the fire. Maybe the first tanker could be a little aircraft such as C130 and then as second tanker the B747.
