MH370 debris- lack of fouling

It seems that the wing (flaperon) part found in the Indian ocean may indeed be from MH370. If this is true, I am amazed at how little fouling there is on the metal surface. Do any of our posters know what sort of alloy is used for wing skins these days, (or when the Boeing 777 was designed), and has anybody got any information on the anti-fouling properties of al/titanium or whatever, alloys? Even if it is not from MH370, there was time for stalk barnacles to grow, but not much else. Pretty amazing.

Most aircraft alloy is L72 Duralumin, I forget what else at this time of night but much better than pure aluminium though that is still the basis.

Snag is that flaperon is carbon fibre; note the straggly strings and wavy line to the torn trailing edge which presumably hit first.

No special antifouling properties even though that's possibly not on the original Boeing spec' !

All this bolleaux about being amazed by surface drift is exactly that anyway; if one has half a look at the military and very powerful phased array radars in the area, as well as satellite surveillance, a lot of people know exactly where the aircraft ended up, crashed or not, dummy debris dumped or not.

There was meant to be 10 tons of gold on the thing but this was not mentioned after a couple of days....

Sadly the up / down profile does seem to fit killing the passengers via hypoxis.

All accounts have the aeroplane still under human control.

A lot of people - inc opposing local powers both with state of the art radar, let alone the U.S. & Russians, maybe Chinese, from space and undisclosed high recce assets -knew exactly where the aircraft went at every step, they just aren't talking; one can only presume they don't want to show their abilities.

No mystery except waiting for ' freedom of information ' if you or I last that long !

IIRC, duralamin is an Al/Cu alloy, so maybe the Cu is antifouling.

It's been in mid ocean so not enough nutrients in the water for algal/weed growth of the sort that grows on boat hulls round the uk coast. Goose barnacles grow anywhere where they can get a grip and be underwater. If the flotsam keeps rolling over, barnies will die in the sun - hence why the barnacles seem to be along edges.

Two tons of gold (2.45 tonnes, actually or 200 gold bars)

It was only in the water a few weeks, That's when "THEY" dumped it to be found :encouragement:

OK, so it is composite construction. Even the outer surfaces? Could there be a special surface treatment like anti-icing paint? Any idea how high it would float? In aircraft composite construction do they use foam sandwich?
Dont want to get bogged down in conspiracy theories, so lets work on the best guess that it was ditched in mid Indian ocean. That long in the water it has to have conventional barnacles as well as the stalk ones, and unless it is flipping daily, even if they die, their shell would still be visible.

Yes foam sandwich is used in aircraft construction, but this looks more like a straightforward hollow foil which happened to act as an air tank; anti-iceing is usually dealt with by applying chemicals, either on the ground or released in flight, so paint is usually just thin & smooth, obviously as hard wearing as poss with weight being watched very carefully.

Don't think there's any specially slippery or barnacle avoiding properties, in early pics the thing seemed to have a good covering ?

What a load of crap. If anyone knew, all it would take is a ship to "accidentally" sail through the debris field and the wreckage would be found, without giving anything away.

Not just my ' load of carp ' sunshine, try reading through the reports on Pprune.

As to why someone hasn't been allowed to accidentally discover the wreckage, that isn't known but the fact is the aircraft must have been on several state of the art ground radars, let alone satellites.
