A Correction to My Skyline Review
I posted a link to my review of the film Skyline on my alternate history forum and it seems I misidentified one of the aircraft deployed in the initial attack on the alien mothership.
The user whose handle is Wanderlust identified the aircraft carrying the nuclear weapon as a drone, not a manned plane. She even posted a link identifying what the specific drone is:
Given how (I assume) the military launched the initial attack using drones to avoid the possibility of pilots being hypnotized by the aliens' lights, including a manned aircraft like the B-2 Spirit amid a swarm of Predators and/or Global Hawks doesn't make a lot of sense. The nuke-bearer being a drone would also explain why it was able to pull the high-G manuevers that it did to evade the alien fliers and gut the alien mothership with the tactical nuke.
Wanderlust also pointed out that since this is a naval project, that would explain the presence of the carrier battle group off the coast. The user whose handle is The Red theorized that the reason the second attack on the alien swarm above Los Angeles included unarmed helicopters and infantry and a relatively small number of manned aircraft (we don't see masses of F-22s or naval F-14s) is that they assumed the nuke had taken out most of the aliens and were just mopping up.
An unmanned first wave followed by a manned mop-up actually makes strategic sense when dealing with an enemy that can potentially hypnotize and disable human soldiers. The flaw in the strategy is a lack of intelligence (the mothership was temporarily crippled, not destroyed), which is often a reason military operations fail. The follow-up attack fails, the carrier fleet is destroyed, and it seems the swarm is triumphant over Southern California.
