Questions about the big white X's seen on closed runways...

In the broadest sense, the X means closed/don't even THINK about landing here.

Does the X mean permanent close, or just closed for now?

For emergencies, would it be okay to land on one anyway? (assuming it was in good condition otherwise)?

I know some close runways are repurposed for drag strips, auto-x, etc. so you'd take a chance trying to land there, especially when there may be some vehicles, go-karts, motorcycles, etc. using the space, not expecting a airplane to land

Are there other styles of symbols marked on the runway (other that the heading digits)?

What might these other 'non-X' symbols mean to a pilot / is there is list of them?

White X is not usable landing strip/runway.
permanent or temporary..
It is meant to make it absolutely clear that there is no active landing strip/runway, may not even have services to refuel or repair.. its not a runway at that point.. but it looks like one.. hence the X

If its really an emergency one lands the plane where gravity brings it. there's nobody who will fine you for putting it down in a non airfield place if you have no other options.
Military Airfield
Golf terrain
high way
drag strip
closed airfield

Whatever it takes. Landing takes priority, sort out the situation of the landing site later once everybody is safe on the ground..


here is another one for Seahawk, make his ticky ticker go boom-didi-boom (Allo Allo pun) :P

Captain Williams, flying a F9F Panther, downed four Soviet (Russian piloted) MiG 15s in the longest dogfight in US aviation history.

Truly this man has “The Right Stuff.”

I Can't stand that Dark whatever bunch of YT channels, the speed talking narration drives me nuts.
I keep blocking his ass, but he comes up with new Dark something channel names

Confiscated Hawker takeoff--but it must have landed at one time.

Pretty sure that was a "hold my cervesa and watch this" moment

Every engineer knows that if F1 allowed "active surfaces"(vertical lift wings and rudders), the speed threshold for driving any track would be limited to the occupant behind the wheel with the ability to handle g-forces.

Active lift would make tractor-trailers much lighter or fuel efficient on downgrades and slow braking.
Somehow the concept has never been discussed .

G forces in F1 are already an extreme affair, I bet they do more neck bridges than Fighter pilots for the simple reason: Lateral G's are harder to counter.
Head weight increases and pivots on the neck.. vs Vertical G it simply pushes down on the vertebrae?

I kinda doubt that tractor trailers go fast enough for active Aero to make much difference,(90kph in europe, 65mph in US?) it would take massive wings to ge aero to do anything, which will drive up cost and drag and I don't think that any of that is feasible?

Big, with roomy compartments to compete with luxury ocean liners. no one wanted it.

That's some hard cornering!

contra rotating props, it was probably a lot noisier than ocean liners :D

A friend flying the flight told me they had to slow to 160 kts at flaps 20 to keep the radius of turn down maneuvering for the “4”
