Is the Delta Flight Museum in Atlanta worth a visit?

I've heard good things, and it's definitely on my 'list' of places to eventually get to. They've got a full-motion 737 simulator there you can book time in, just be ready to :staredog: at the pricing.

You're also not *too* far from the Museum of Aviation at Robins AFB. It'd definitely be a day's trip.

It's a myth that rubber tires help vehicles from being struck by lightning. It might help the current choose a better path through a tree or a rod nearby, but the current can travel tens to hundreds of miles. A few more feet around a wet tire isn't that much.

That and its steel belted rubber tires. The steel helps current find a path.

Dear diary, I got another erection today at work. SO embarrassing, but kinda hot. The CO asked me to fix up his dress uniform. I had stayed late at work to move his badges 1/8" to the left and pointed it out this morning. 1SG spanked me while the CO watched, once they caught it. Tomorrow I get to start all over again...
I know some aircraft have grounding wires between the tires. Literally just dangles there and bounces off the ground.

I might be super-wrong about this, but I think all that other stuff (steel belts, grounding wires) is the important bits. I've learned a tiny bit about electricity and the bit where a conductor, something neutral, and an insulator's conductivity is like to the power of 9, zero, and the power of -9 stuck with me.

The Museum of Aviation sounds tempting but since it seems like a subset of the National Museum of the AF in Dayton (which is only 2 hours and change away) I’ll save that for some other time. If I end up going to the Delta museum I’ll be sure to report back to the thread.

There are no insulators, only very bad conductors

Vacuum isn’t a conductor.

It’s true that electricity can arc through a hard vacuum, but the vacuum isn’t conducting them.

Of course, it’s also not an insulator, for it does nothing to halt the flow of charge.

Yep. It's juuuust insulated enough that some charge can build up and you better ground that fucker before you fuel it, not enough to stop lightning.

it's true that rubber is a better insulator than air but also the lightning just jumped through like a couple miles of air at least. i don't think that one chunk of rubber the size of a dishwasher at the last second is what's gonna stop it

The idea isn’t to stop lightning dead in its tracks.

The idea is that the plane doesn’t become charged via contact with the ground so it doesn’t act like a high point on a big flat field.

It still doesn’t work.

Well don't you know I'm caught in a trap?

Well, fortunately Aluminum is a really good conductor, so it'll conduct all them 'trons safely around the delicate meatbags in the plane, same reason/misconception for why you're safe in a car, you're not really in the flowpath, not that rubber does poo poo all to protect you.

I heard the new composite super-planes have a conductive mesh embedded in the composite to provide this effect, us that true?

In the mid 2000s a ramp agent at Seatac Airport got lit up pushing back a Horizon Airlines plane that got struck. It traveled down the headset line. I was on my way to work there when it happened and saw the lightning bolt.

I can't find any articles on it now, but there was a different one:

Can confirm. Even the composite panels on metal planes have it.

Yeah there's a reason why airports go full ground stop when lightning is in the area.



You don't want to be the shortcut to ground that the lightning takes.

FLIGHT SAFETY TIP: Fatties out first

Larry Walters' story is pretty good, and as an aside so is the rest of John Bois' Pretty Good video series. Even if you're not a sports fan, he tells entertaining tales.

In unrelated news, a while back a bunch of you guys were asking which airline would be most like to collapse after the WOW Air debacle. The answer to that question is, Jet Airways in India. Lessors are moving to repo their aircraft and have been doing so all weekend; it's possibly only a matter of time before it all comes to an end there.

I don't like you because you're dangerous
I was in a plane struck by lightning in flight once, it was downright foreign how sharp and non-reverberating the sound was. It was one of those moments where your brain fails to match the experience with how it understands reality should be.

The other time I felt that way was when a friend took me sailing, and a full size cargo ship probably a mile away blew its horn (wrt. the loudness)

Type ratings in the US don’t have currency requirements per se; The aircraft owner(s insurance agency) is most likely going to require a certain level of currency before they’ll insure the aircraft, or the operating certificate of the airline/air taxi will require certain currency as part of their issuance, so there is a de facto currency requirement.

You can absolutely hold multiple type ratings.

You would expect the pressure on the METARs to track with temperature then, wouldn't you?

edit: a front did go through... seriously odd that the pressures weren't significantly different too?

I went looking through news and haven't turned up any stories of actual repossession but if the deadline on the 10th passes without an investor I imagine it'd be basically instant at that point?
