Galvanic corrosion?

Rookie mistake.

There was also the opposite problem that was explained in Command and Control; a few types of bombs had a little foil strip inside the core that acted to absorb neutrons and stop a nuclear detonation. There was some clockwork-like springs and a mechanism that wound the foil strip up and pulled it out of the core when it was to be armed and used.

Unfortunately those little foil piece started corroding and nobody knew until a few decades later when they were decommissioned and it was realized that the mechanism would not work and the foil would not be pulled out and the nuke would not go off. It affected a huge percentage of the US arsenal and would have rendered them all complete duds.

Four Nieuport 11, two Sopwith Pups, and one S.E.5. They're flown in a C-17 to participate in the commemoration for the 100th anniversary of the Battle of Vimy Ridge.

An An-12 from "Cavok Air" just overflew Northern Virginia at 26,000 feet and it sounded like it was at 2,000. drat, Russia/Ukraine, you noisy.

Dulles has also been an Antonov hub recently - United must suddenly be needing a ton of GEnX for their service depot there because I've seen An-124s in and out of it at least three times in the past 90 days.

One even left past midnight there last night headed for SNN, probably to the chagrin of everyone trying to sleep in a house or hotel nearby.

New drone rules for Canada announced and effective immediately.

Highlights:
Within nine kilometres of somewhere aircraft take off or land

Most of it is pretty basic but the blanket 75M (250') of buildings and people seems a little extreme at first glance. There is rural park I fly at which is truly in the middle of nowhere (miles from the city), but they have a clubhouse which would be classed as a building I am sure, but at first glimpse it seems like that would be unacceptable now.

The Nieuports and the S.E.5 are 7/8th scale; the Pups are full-size I believe. The C-17 is big!

What makes it even funnier for me is that the builders didn't forget to put on the galvanic corrosion inhibitors, they were told to remove them by the military because of budgets cutbacks (or overruns, one of the two).


"Hmmm, we're running out of money here, what should we remove to save costs? Oh, I know, how about the incredibly inexpensive system which prevents the vessel from disintegrating at a molecular level!"

The pilots are heroes they wrestled the plane out of an uncontrolled barrel roll

I actually witnessed an AN-124 crew breaking down a wheel assembly out on the freight ramp in MSP with hand tools and a sledge hammer.
They had the new tire leaning against the cargo ramp.

We stopped and offered to let them use some air tools in one of our hangars, but the language barrier was the problem.

PittTheElder posted:

Meanwhile they were also experimenting with the first bomber aircraft, and the lack of engine power led to just ridiculously proportioned vehicles. The Gotha G. V had a longer wing span and more wing area than a Ju 88, by a big margin.

Next they'll bring back Metroliners.

I was watching some short documentary clip last night about the An-124 since I know little about them and apparently it's typical for the crews to do their own maintenance and repairs when on the ground (and of course keep a huge supply of parts on board for obvious reason) - also I came across the anecdote on airliners.net which I thought was great...

Ok people a prop fell off.

Did you not see this story?!?!?


A jet at 35,000 ft gets tumbled by an A380 1,000ft above it! Takes 10,000 ft to recover! It was full of people with very brown pants now. This could have been a complete disaster. The pilots are heroes they wrestled the plane out of an uncontrolled barrel roll without engine or APU power and were able to make it to a runway safely. Has wake turbulence ever been such a problem at those altitude and cruising speeds before?

HookedOnChthonics posted:

My favorite of these is definitely the Linke-Hofmann R.II, which had a wingspan of 138 feet and used four interlinked engines to drive a single, 22-foot propeller, the largest ever used.



It's like a single-seater biplane the size of a 737.
