Here's a fun one. Why were tankers painted green and Grey in the 90s?

Did they belong to the army?

a reply to: TerryDon79

No, they were all Air Force.

Hush Sam. Where do you think the idea for the question came from.

a reply to: Zaphod58

Camo?

a reply to: TerryDon79

Some dumbass Pentaweenie that probably had never been closer to aircraft than the ones going by into National airport decided that instead of Mohammed coming to the mountain for fuel, the mountain would come to Mohammed, and would do it really low.

So flying below radar to refuel, type of thing?

a reply to: TerryDon79

Yes. Low enough that when looking down from another aircraft the green top would blend with the ground and be hard to see. And when looking up the grey would blend with the sky.

Funnily, as soon as they painted the KC-10s green any remaining warranty was immediately voided.

In the second world war the Germans had a clever way of making their propeller driven aircraft 'stealth' against the equipment we used to detect them before the advent of radar.This particular trait was still used by German plane makers as recently as the C160 Transall that made them distinctly 'German',what was it and how did it work?

Just a wild guess but does it have something to do with the acoustic mirrors England had to detect incoming aircraft and a German propeller design to minimize sound propagation?

A very good guess.Not mirrors as such,but these state of the art devices still being used in WW2.......



And also yes to propeller design..............

Those are one hell of a pair of hearing aids. I think I need a set of those.

a reply to: Sammamishman

Yes it is to do with the listening horns and the sound from the aircraft's engines,but how did they use it to fool the horns?

They played the sounds of birds to drown out the sound of the engines?

No birdsong I'm afraid.I've been trying to find a video with sound to make it a bit easier for you,sadly I can't find one.Oh and I'm not talking about the sound the Stuka dive bombers made with that thing bolted to the bottom of them,this was just multi engined prop planes.

They flew with unsynchronized engines to fool the acoustic radar.

Here is one of the oddest Aircrafts ever.

What is it called and who made it?

You da man Zaph! This explains the droning sound or beat note made by them,caused by using assymetrical props with different pitches.German built Transalls did this but the French built ones didn't.
