Every Planes have one site in wing tip called Surge tank, its for ventilation of fuel tanks. Sometimes when plane need so much fuel we turn off somes Circuits Brakers and fill so much kerosene. And its go to surge tank on tips when the wing bonds or vibrate and fill off the plane by NACA intake. Its "normal" procedure ^^. This its prohibited of course... xD. Im aviation mantenaice engereering, Im not english speaker so forgive my bad english
This explains a picture I saw in Airways magazine once of a small, crude wooden shed out on the grass between runways. It was only big enough for one person to stand in and it had a big sign on it that said "NO SMOKING".
Just to clarify to all of you people. When fuelmis borded for these long trips, the wing tanks are filled to the top. You can fuel them that precise so Boeing designed a feature where the excess fuel is automatically dumped from the valves. You can see this is one of Ben's videos at SXM
You can see water spray at 01:33. But the fluid which is coming out of the left wing is definitly fuel. I know it because the 747 already lost Fuel on its parking position one hour before the depature. The fire brigade had to secure the plane ...
@stevewinslow - another nice video of a great aircraft. Yes you are totally right about the fuel. Its coming from the surge tanks vent and is a result of a slight over fuel of the main wing tanks. It not uncommon and occurs on taxi & takeoff on all heavy Boeings that have been over fuelled. Aviation is a complicated business
All Passenger & Cargo aircraft is designed to dump Fuel for emergency situations so they can land, Its not dangerous & its it does not ignite that easily it uses Kerosene, I don't know why the ground crew would overfill its fuel tanks as the aircraft has its take off limits of how much it should weigh before its departure....
@Cargospotter at 0:15 the fuel dump nozzle is clearly visible and there fuel flow. Interesting, while throttling up at 0:57 you can see something flowing from the nozzle. I still hope it was only water after.
fuck off..

Looks like water spray!!! Sometimes water might get trapped in gaps of the wings!!!

Looks like water spray to me. Pretty sure the wouldn't dump fuel while on the ground.

I can't see any fuel, only water spray. It is to dangerous to dump on ground.

I am pretty sure it is not just water spray. You can see it clearly

Even if they were overloaded with fuel wouldn't it make much more sense to dump it after they were airborne?

Nice one but isn't that dangerous? Or is the aircraft designed to dump excess fuel, I would be scared about it igniting :o
