We ask a lot of that airplane seatback in front of us. It has to be a tray, a TV, as far away as possible (and not sticky), and now it might soon contain an airbag.
Here’s a story from the always interesting Popular Mechanics website: Airbags on Planes: Will a New FAA Regulation Pave the Way for Airbag Seatbelts, March 12, 2009.
Here are some related FDA documents on airplane cabin safety, Fact Sheet and the 2005 regulation. There is a lot more out there, so go forth and research. One day that seatback will connect us to a Web browser, but use your headphones, please.
