Wow, is this a bad idea:
The Luggage Locator is an innovative product that travellers or anyone can use to locate items. It has been specifically engineered to help people find their luggage quickly and can also be used around the home or office.
A battery operated, two unit system, the Luggage Locator consists of a small transmitter about the size of a key chain and a lightweight receiver that attaches to any luggage handle. With the simple push of a button, the transmitter activates the receiver causing a bright flashing light and loud chirping sound. Locating your luggage after a long trip has never been quicker nor easier.
Anyone care to guess what’s most likely to happen if a piece of luggage in an airport starts flashing and chirping? I think it’ll be taken out to the tarmac and blown up using remote controlled bazookas.
