Cars keep rolling, planes drop from the sky with no gliding ability...


Seems totally legit.

I could understand if they mentioned an airport nearby in the first 9 minutes but they did not. Why would a plane be that low and banking like that? They could have made an emergency landing somewhere easily on mechanical power alone.

Exactly what I said. I guess in this movie's world an EMP can break the laws of aerodynamics and hydraulics. ...and make cars that don't even have computers stop working. Someone should be tooling around in some classic muscle cars at least.

It's funny how cars kept coming but the plane stopped in midair. One or there other people.

I also love that the ladies must be scavenging nail polish and eye liner so they can keep up their "look". At least that is implied by the fact that the makeup and polish never comes off or looks bad. Even my 13 year old soon noticed this.

With zero controls, if a plane had been performing a manoeuvre or a minor correction, It would have been stuck in that position and eventually a gradual decent due to flaps being up (or down) when dipping / banking the plane would have turned into a plummet as they would not have been able to level the plane out for a glide

Of course this is ASSUMING that the pilot stick is not (as you indicated) fully mechanical, I am guessing there is an element of power steering controlling an xxx tonne plane

Hydraulics won't work without power, you aren't gliding anything in without power that size..and I'm sure dayton has an airport, if not they're not far from Columbus or Cincinnati which would explain the altitude. And sure, old cars without computers would run after the fried electrical was replaced.

Planes are designed to glide a certain distance for every foot dropped

reply

Yes, but if one happens to go below stall speed then the wings will tilt, the plane will drop out of the sky.

But come on, folks, it is just a movie, not intended to be aerodynamically correct. They just wanted to illustrate a point, loss of control.

Glide ratios mean nothing when you cannot control pitch, yaw and roll of the plane.

reply

well I think yaw stupid

Not when the avionics are dead from an EMP blast.

I'm not sure about 747s, which I think is what crashed in the movie, but many aircraft no longer have mechanical linkages between controls and control surfaces.

Damn I learned a lot about planes from this thread alone..

Or did you? Who knows if any one of these people have any clue what they're talking about.

Wright Patterson AFB is right outside Dayton and Dayton Int is there as well.

Most modern aircraft and especially military aircraft have RATs or Ram Air Turbines which can be deployed in the event of a complete power failure. Some RATs are designed to power hydraulics mechanically with no electrical input. It's true that a fly by wire aircraft with no mechanical linkages couldn't keep flying very well if at all in the event of en EMP, some aircraft however have mechanical backups to the electrical controls which can be selected by the pilots if they lose power. Any ability however to keep a large aircraft in the air using mechanical controls is completely reliant on hydraulics. There have been instances of airplanes suffering complete hydraulic failures and crashing and the stick or cyclic is actually bent as a result of the pilot(s) trying to control the aircraft with no hydraulics.

I haven't seen the movie and they may not mention in it in the movie but when Sully landed USAir 1549 in the Hudson they had lost all power but were able to deploy the RAT in time to control the descent.

All newer planes are fly by wire. meaning computer controlled. The flight stick will do *beep* all if an EMP went off, also the reason for being fly by wire is because the planes are very unstable due to the design, planes are design for fuel efficiency rather than stability.

It's a movie. It's make believe. Even if they make a movie based upon actual events, they still "Hollywoodize" it a bit, just for entertainment value. I have seen planes from small Cessnas to F-16 Fighter Jets to an Airbus 321 to a Widebody 787 do and act squirrelly under different situations and conditions. That is why there are actual Hardcover manuals in the cockpits to address things and situations that come up. Trying to guess what the actual circumstances are with this plane in a movie is for sure a no win battle. One thing you can be sure of is the fact that they made it crash that way for effect, not for real life feel. Keep in mind, if this was real life, a team of Engineers and Investigators would have to reassemble what was left of the plane, read the data from the Black Boxes and surmise with a best guess with all the available information as to why the plane acted and crashed like that. But in this movie, I am sure they are all long dead. All we know for sure is the plane went Boom.

Boeing planes have cables to control surfaces, but Airbus ones use Fly By Wire (https://en.wikipedia.org/wiki/Fly-by-wire)
Since the aliens used this EMP weapon, I suppose the plane we saw falling like a rock, was an Airbus :-D

Well, this is a video of a 747 that had its on board cargo shift in flight. There is more than a passing resemblance!

I remember that accident, and I'm not sure about your point if it was an answer to my post. Aliens in the movie didn't shift weights within aircrafts

reply

Oh, not a reply to your post at all. Just comparing the real accident v. the movie crash. In some ways it looks like the CGI guys copied movements from the the loss of control 747.
