Watch What You Eat

AirlineMeals.net has garnered a thriving community of hardcore frequent fliers who love to catalog what they eat when they fly.  Their easy to use interface allows you to peruse the in-flight meals offered by hundreds of airlines from around the world.  While this is pretty cool, the best part of the site is the photos they of have airline food from yesteryear - their catalog dates back all the way to the late 50's (a 45-year-old TWA meal is featured above) and it doesn't look like airplane food has changed very much since then.  Other neat sections on the site include the rundown of food found in airline lounges and their shots of the kitchens where all the food is prepared.  There's also a section on those specialty meals that its always a good idea to order so that you get served first.
