High School Student Launches a Trash Bag Aircraft

An anonymous reader writes with a great write-up of a project completed last month by Manuja Gunaratne: "A high school student at Advanced Technologies Academy in Las Vegas, Nevada managed to launch an aircraft using trash bags. The trash bag aircraft traveled for hundreds of miles and rose to thousands of feet while capturing thousands of images of the Earth. The trash bag craft consisted of household equipment and only cost $50."

    Nice job. FAA letter on the way and your education will now be complete. You may learn about high speed collisions and hazards to air navigation. I know it was probably day VFR, but controlled airspace is 1400 AGL (except in the mountains). Part of doing this correctly is to play by the rules and there are a lot of them.

    Seems every geek modeler with enough sense to build a UAV ought to be wise enough not to endanger the flying public.

    As long as they weren't in a restricted zone near an airport, I don't think this balloon and it's 1.6 lb payload violated any FAA regulations:

    Except as provided for in 101.7, any unmanned free balloon that—

    (i) Carries a payload package that weighs more than four pounds and has a weight/size ratio of more than three ounces per square inch on any surface of the package, determined by dividing the total weight in ounces of the payload package by the area in square inches of its smallest surface;

    (ii) Carries a payload package that weighs more than six pounds;

    (iii) Carries a payload, of two or more packages, that weighs more than 12 pounds; or

    (iv) Uses a rope or other device for suspension of the payload that requires an impact force of more than 50 pounds to separate the suspended payload from the balloon.

    (b) For the purposes of this part, a gyroglider attached to a vehicle on the surface of the earth is considered to be a kite.

    Knock a Cessna out of the sky with your trashbag-levitated picture taker..

    If your flying a Cessna and you can't see and maneuver out of the way of a floating collection of trash bags, you have no reason to be flying in the first place.
