About this oil slick...do planes actually carry enough oil to make a size able slick in the event of a crash like this?

I'm not an aviation guy, but I can't imagine that much oil on a plane...

They carry enough jet fuel, which is a very light oily liquid similar in many ways to diesel fuel or kerosene, to make a substantial oil slick. They also have synthetic oil for engine lubrication, but I have now idea the size of the reservoirs for the oil.

The 777-200ER can carry up to 45,000 gallons of Jet-A fuel, which is basically kerosene. A flight will typically not be fully fueled, just enough for the flight and a reserve at the end, but still, it'd make a hell of a slick.

Even if you want to be a literalist, Jet-A is very similar to Fuel Oil no. 5, so you could still call it an oil slick.

Yes; it's called jet fuel, and the 777 can carry more than 30,000 gallons of it, up to 47,890 at take-off on long range versions.

Gotcha. Thanks for the informative answer.

I was trying to figure out how deep the water is in the crash area.

Is it about 150 feet ?

I didn't know a crash area had been determined.

They got the data recorder from AF 447 in about 13,000' of water. I bet this is a good amount shallower.

The data recorder is what we really need. I thought it sent off 'pings' for a while too.



Edit to correct depth of AF flight recorder find, about 13,000 ft down as posted below.

If it is roughly in in the Gulf of Thailand, the max depth is only about 240 feet.

I thought it was only 10 or 12k deep. Either way, that's a lot of water.

Report on Huffington Post says they are thinking the plane 'disintegrated' at around 35,000 feet.

Is that even a thing? Can something as large as a 777 just dissolve? We would be seeing a smattering of debris right?

Uh, yeah, I would think there'd be a ton of debris. it'd be all scattered to hell, but still. I mean, it's not like it was entering the Earth's atmosphere at 17,000 mph, right?

"Disintegrate" simply means "to lose integration," in other words, to break apart. Although rare, it does happen. Severe turbulence, extreme control-surface movements, explosion, etc. could cause it. Generally there would be a large debris field, including floating objects like seat cushions, visible on the surface, which is why many are suggesting that there was NOT an in-flight break-up, but it's all still just speculation.

Dissolve? Not likely. Rip itself apart in flight? That has happened. An example is China Airlines 611.

Pieces will be found, but if it cam apart at 35000 feet, they could be very, very spread out.

Huffington Post is grasping at straws. There is about as much evidence to support that as aliens abducting it.

At this point there is no evidence that supports any explanation. So far all we know is that the ACARS link got cut off after a 650ft drop. That is it. Unlike the Air France crash that is very very little to go on.

Until they find the crash site, anything that that anyone comes up with, will be as one of my Aerospace Engineer Profs called it, a Wild Ass Guess.

I don't think they're using the word the way you think they are. In-flight disintegration (to me, anyway) just means that it broke up into some number of very roughly equally sized pieces. It could mean anything from "broken in half" to "there aren't any pieces left that are bigger than a square inch".




Those who forget the pasta are condemned to reheat it.

This spurred me to check out the flight recorder from Air France 477. Dumb bass pilots stalled the jet from 27,000 into the ocean.

Too be fair, they likely didn't think that you could stall an Airbus. If everything is operating correctly you can't put a control input in that would stall the airplane. They didn't realize that they exited normal flight control laws.

Perhaps the reliance on computers to protect pilots from themselves isn't the right idea. Or perhaps there needs to be a more obvious indicator that the airplane is no longer in normal law.
