Pilot has close call with a train

Khufu says...

well done... but maybe getting a chain out and towing the plane off the tracks should have been step one? Wouldn't have been as great a video though.

Most People Don't Know How Bikes Work

fuzzyundies says...

In my M1 (motorcycle endorsement) class, we learned this as "breaking the plane". There's a lot more force involved so you kinda have to consciously do it above a certain speed. Knock the front wheel in the "wrong" direction so that the bike falls into the turn in the direction you want.

Can Spinlaunch throw rockets into space?

Using a mountainside might help with structural integrity, but it's not likely to give much air resistance advantage if I'm reading the math correctly. The 5 highest peaks in the US are all in Alaska and and range from just under 5km to just over 6km. Commercial jets using air resistance/density for lift fly at about 10km and even at 38km aerodynamic lift still carries 98% of the weight of the plane (https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line)

Air density is halved at 5km compared to sea level, but air resistance doesn't diminish as quickly (due to it being multiplied by velocity squared and drag coefficient), and only becomes irrelevant (for short-term purposes) around 100km at the Karman Line.

If we had a 5km peak in Florida, the lack of logistical costs might make the benefits worth it, and if we could build on one of Equador's 5km peaks, then there's the further advantage of equatorial location for optimal rotational advantage (part of the reason we launch from South Florida)

Airplanes Emergency breaking is pretty effective

Considering the immediate circumstances I think it's instead a *win to have avoided major damages to both planes seeing how close the Red Bull was closing in on the white Cessna) .

So this float showed up at the Popcorn festival/ parade

Am I missing something here? I always thought memorials were supposed to be sad or solemn. To @noims point of humor, I don't see any attempt at humor here. Just a low budget float without an art director.


Speaking of dark humor though, it's not as though the Kawani's are doing their thing with their go carts dressed up as 747 planes pretending to crash into the float.

I ask genuinely, why are the tortured figures in the holocaust memorials not being derided as "celebrating their torture" ?

How is depicting a wounded person different than a wounded building in terms of war memorial creation?
(not the diff btween a building and a person) just the bit about why it's suddenly offensive to show something that was attacked.

The perfect gear up landing

America really flew the U-2 spy plane off aircraft carriers

newtboy says...

Unconvinced.
Why would they try to land on an aircraft carrier, breaking the plane every single time by scraping the wingtips off on the deck? In air refueling means it would never be required, and a total lack of stealth makes it just stupid, landing strip width makes it incredibly difficult to land a plane over 3 times the wingspan of an F16, especially one as in precise and hard to fly as a u2….and impossible to store off the deck, making the carrier useless until the U2 was removed.

On land they had chase cars that drove under the wings at landing, installing the wheels and/or keeping the tips off the ground.

Not trusting this internet source…beware unknown sources.
There’s a reason there wasn’t one shot of a successful landing, the best they had was a 3 point landing with the wing as point 3. At best this was a failed test, not a functional program.

The Plane That Will Change Travel Forever

StukaFox says...

There's a major problem with this design that was just glossed over in this video: the windows aren't there for you, they're there for the pilots and flight crew to see what's going on outside the plane in the event of an issue. You can have all the cameras in the world on that thing, but no civilian pilot is going to get on a plane without being able to see what's outside it themselves.

Also, watch this video that explains why no one designs new prop engines and why we're still using a basic engine design from the 1950s. Now take these basic issues and them multiply by billions of dollars. This idea is a total all-or-nothing for Boeing/Airbus and there's no chance in hell that management would ever go that far out on a limb.

Fire pilot makes epic drop at an extremely low level

WmGn says...

Does anyone know how much the plane's weight decreases during the drop, and how that changes its handling?

(I'm trying to work out how much harder this is than, say, coming in for a landing run.)
