<p>An inflatable balloon and signalling components attached thereto are stored within a closure member held assembled with a breakaway housing to enclose an inflating device for the balloon. Removal of the closure member initiates inflation of the balloon, operation of the signalling components and separation of the breakaway housing enabling the positioning of the inflating device for aerial launching of the balloon with the signalling components suspended therefrom.</p> |
