The airline industry was highly regulated until the late 1970s, when deregulation in the United States started a trend to liberalize air traffic around the world. Until then, ticket prices and the destinations an airline was allowed to serve were the main subjects of regulation. Airlines were regarded as important agents for economic growth as well as ambassadors of their home countries abroad, and regulation was to provide stable economic conditions for this promising new industry.

Vollrath makes the most of the confined setting -- something that could hurt a weaker filmmaker. In some respects, 7500 must have been easy to produce. A single location, small cast, and minimal set dressing all speed the shooting process, but these things come with restraints. When all the action is set in an airplane cockpit, there are no astonishing backdrops or special effects to use as a crutch. The weight of the storytelling is relegated to the script and its handful of actors.

We expect tragedy, whether its man-made or natural, to come fully illustrated - collapsed buildings, mangled limbs, charred bogies of trains, airplanes crashing into skyscrapers in front of our horrified eyes. Flight MH370 has none of that. Days after the tragedy we heard about a "yellow object" floating in the sea. Perhaps an oil slick. But all we have seen on 24-hour television is the footage of anxious families huddled in Beijing airport, glued to cellphones.
