“Airliner Sky Battle” (** out of four) was a relatively generic action thriller about a group of ruthless Russian terrorists (Daniel O’Reilly and Ego Mikitas) who hijack a commercial American jet and intend on crashlanding into a nuclear power plant near the White House that will devaste the Eastern seaboard; fortunately, some military passengers (Wade Baker, DeAngelo Davis, and others) onboard attempt to overthrow them and save the world. Not bad as these things go, with some zippy action and decent stunts and visual effects, but limited by its low-budget and secondhand production feel. Not all that different than Paul Greengrass’ cinema-verite “United 93”.
