** The LA ship doesn't fire a second pulse. It shoots the targeting beam, fires the pulse, then keeps the targeting beam active for at least a minute, even after all of downtown LA has been flattened. Could be a production mistake, of course.

** Just because it was written on a Mac doesn't mean it has to affect a Mac. The computer is just a tool to send a signal into the alien system. We can send computer signals through phonelines, radios, or even optic nerves. The hard part is the interface. Since Jeff discovered that the aliens were interfacing with our systems, deliberately or not, all he had to do was figure out a) how to reverse that process and b) discover how the alien systems arranged their command protocol structure. From there it would have been simple to scramble that structure at least for the time needed to destroy the mothership.

** The "firecracker in your hand" explanation given in ''Film/{{Armageddon}}'' applies here. That not-exactly-small nuclear explosion inside the mothership heavily overpressurizes the interior of the hull (a sealed container) in less than a second. Nothing is going to hold ''that'' in. It may not instantly disintegrate into tiny pieces as shown, but it's still getting torn asunder.

** Those panels don't look particularly weak, they're easily half a building thick. Punching through them would probably require a bit of firepower.



* How do the city destroyers choose their obliteration targets? At first I thought it was generally the tallest and most central building in each city (the fact that U.S Bank Tower in LA and the ESB in New York are the targets there supports this somewhat) but then that theory is blown apart by the White House in D.C being the target there (it is not the tallest building in the city by a long shot, the Washington Monument is the tallest in the city proper, nor is it centrally located, the Capitol Building is considered most central). Other scenes in the movie, especially news broadcasts seem to also dispute this (in Paris, the target isn't known, but it isn't the Eiffel Tower, which is the tallest structure in Paris).

**The LA ship firing a second pulse I think is a mistake, because there's no reason to fire it again as the wave is already propogating past Downtown and into the surrounding areas. Why the White House starts blowing up when the beam fires is probably because unlike the US Bank Tower and ESB, the White House (to my knowledge) is primarily a stone structure with steel interior framing and is much older. The ESB and USBT are steel structures and are relatively new. The beam caused the building to start losing structural integrity and catch fire. The beam that is fired is likely a "designator" beam, then the main pulse rides down the beam to the target. Until the main pulse is ready, the beam is inert.

** He is also seen with the president several times prior to the initial attack. At any of these points he could have brought up what is now extremely relevant information.

** It may have something to do with the beam intensity and building materials. When they fire at Area 51, the base shakes and the lights flicker, indicating some sort of interference. However, what gets me is how long they keep firing the beam after the pulse. The LA ship keeps firing the beam until the blast wave has gone a few miles in all directions. However, the NYC and DC ships seem to cut out immediately after the pulse.

[[folder:The beam and the pulse]]

* There seems to be some inconsistency as to how the primary weapon of the aliens works. The basic manner seems to be that the ship creates a downward beam, and then sends a pulse down. 3 times out of 4, it's the pulse that causes the destruction, not the beam, as we don't see any destruction begin until the pulse appears and makes contact with something. However, in the White House destruction scene, the White House begins blowing up when the beam appears; the pulse is still shot down but the White House is already exploding. In the other 2 city scenes, the explosion doesn't begin until the pulse makes contact with the building. In the self-sacrifice scene toward the end, the guy pilots his jet right into the beam no problem, until he is near the tip of the weapon: When the pulse emerges, both plane and the alien cannon are destroyed. There seems to be inconsistency here.

*** For what it is worth, ''Resurgence'' (along with jossing some other explanations thrown about on this page) indicates that the city destroyers ''do'' have troops on them. Presumably the mothership troops were intended to reinforce them (as ''Resurgence'' also indicates that their ground troops are ''not'' given shields, and consequently can be killed by humans).
