Ok ... to put a pin in the whole Plane vs. Dome Discussion, here's a bit of mathematical analysis. For the purpose of the analysis I'll assume a few things ... some of which is *not* supported by what we know (from the show) and may even be contradicted by visual clues we have been given.
Assumption #1: The dome is a "perfect" hemisphere (above ground.) (This seems to be contradicted by other visual cues.)
Assumption #2: *All* of the forward momentum of the plane is absorbed during the impact and the debris falls straight down from the point of impact. (Clearly from the video, this is not the case, in fact, the debris rebounds backward.)
So, with those assumptions let's set the radius of the dome to 5 miles and the altitude of the plane at 1500 feet AGL.
In this case, the debris would fall 42 feet from the intersection of the dome and ground.
Now, consider that a hemispherical dome with a radius of 5 miles would be able to cover almost all of Manhattan and at least parts of Brooklyn, Queens and Sopranolandia. Furthermore, It would reach a height of ~26,357 feet AGL. Give it another half mile or so and you can cover Mt. Everest.
So, for now, let's keep the radius at 5 miles and increase the plane's altitude to 2500 feet. In this case, the debris falls ~118 Feet from the intersection of the dome and ground.
Given that a 5 mile radius is probably overkill to cover sleepy little Cleaves Mills (or whatever the name of the town is) and it's outskirts, let's cut that in half to 2.5 miles, which would be plenty big enough to cover a typical small town/city.
R= 2.5 miles; A=1500 feet; then Distance = ~86 feet.
R= 2.5 miles; A=2500 feet; then Distance = ~239 feet. ... or approximately 3/4 of a football field.
So what do we learn from this? What we saw on screen is indeed *possible,* but only if the dome is a full hemisphere and is far bigger than it needs to be *or* the plane was flying significantly lower than what is typical for an aircraft of that type. ... Like crop dusting altitude.
Go ahead ... feel free to check the math.
PS: All that being said, what we actually saw on screen (crashwise) is much more consistent with the plane smacking into a dome that has cylindrical walls and a semi-spherical top. I mean ... it's almost like SFX department couldn't figure out how to smash a plane into an actual hemispherical dome, so they did the best they could. Edited by HDTVChallenged - 6/29/13 at 4:41pm
