How could the top of an airplane fuslage be on fire without exploding?

In summary, the crash of a 777-200ER is mysterious because it doesn't seem like the fuel would be stored up in the airframe. The cause of the crash is still under investigation, but it's likely that the fire started in the cabin and then spread to the fuel.

Everybody seen the crashed 777 picture right? Just weird, because I always thought the fuel would be stored beneath the airframe and inside the wing.

How did the fuel get "up there"?

electrical fire, there is plenty of insulation and wiring up in the top of the fuselage, along with everyone's luggage that can burn.

I was thinking of all the laptops that burned up. It would be a great ordeal if my laptop(s) were destroyed - even with them backed up.

There wasn't any fuel up there. That's just where fire burned through the cabin.

Here's one of the first pictures taken by one of the passengers. There's a fire that's started but it's not on the top.

Plenty of fuel in the top of an airliner, including foam and plastic head-liners. Lots of smoke from plastic and once it get going, it burns hot.

No disagreement there. The OP seemed to think that jet fuel is stored up there. That's definitely not the case.

Fuel is however stored below the passengers in a 777-200ER, which was the type of plane that crashed. The 777-200ER has a 26,100 gallon center fuel tank that spans the two wings.

Presuming that the landing gear was down and locked when the plane pancaked the ground, the gear should have ended up being pushed into the fuel tank. ?? It seems to me there would have been more fire lower down and there wasn't.

Edit. OK so the tail, landing gear and one engine were ripped off. In photos the other engine appears to be off and laying slightly in front of the wing.

DH's pdf shows the fuel tanks located in the forward half of the wing in the fuselage area on page 1 and the landing gear is located just behind that (page 10).

Two reasons that I can think of for the reduced initial fire. Since it was at the end of the flight, there wouldn't be as much fuel remaining on the aircraft. Plus, the video that was released showed a huge cloud of dust get kicked up as it skidded off the runway. The dust probably acted as a fire suppressant. From jtbell's link in the other thread: http://www.cnn.com/video/data/2.0/vi...red-hayes.html

Edit: The video link seems to be no good anymore. Try this one: http://www.cnn.com/video/data/2.0/video/us/2013/07/07/vo-plane-sf-plane-crash-on-cam.courtesy-fred-hayes.html

1. How is it possible for the top of an airplane fuselage to catch fire without causing an explosion?

There are several factors that can contribute to a fire on the top of an airplane fuselage without causing an explosion. One possibility is that the fire may not have reached the fuel tanks or other highly flammable components of the aircraft. Additionally, airplanes are designed with fire-resistant materials and safety features to prevent explosions in the event of a fire.

2. Can a fire on the top of an airplane fuselage spread to other parts of the aircraft?

Yes, it is possible for a fire on the top of an airplane fuselage to spread to other parts of the aircraft. This can happen if the fire is not contained quickly or if it reaches other flammable components such as wiring or fuel lines.

3. What are some potential causes of a fire on the top of an airplane fuselage?

Fires on the top of an airplane fuselage can be caused by a variety of factors, including overheating of electrical systems, mechanical malfunctions, or external factors such as lightning strikes. In some cases, fires may also be caused by human error or sabotage.

4. How do pilots and flight crew handle a fire on the top of an airplane fuselage?

Pilots and flight crew are trained to handle emergency situations, including fires on an airplane fuselage. They follow specific protocols and procedures to contain the fire and ensure the safety of passengers and crew. This may include deploying fire suppression systems, diverting the aircraft to a closer airport, or making an emergency landing.

5. Are there any safety measures in place to prevent fires on the top of an airplane fuselage?

Yes, there are multiple safety measures in place to prevent fires on the top of an airplane fuselage. These include regular maintenance and inspections of the aircraft, installation of fire detection and suppression systems, and training for pilots and flight crew on how to handle emergency situations. Additionally, aircraft manufacturers are constantly improving and updating safety features to reduce the risk of fires on airplanes.
