After several (fruitless) attempts using \parboxes and modifying the maximum length allowed for the text, I think that given the length of the text for the objectives and tasks, it would be appropriate to use a different approach.
One option would be to use tooltips so the Gantt chart only displays a little amount of text (the labels) and the information for a given objective or task will only be visible when hovering over that element.
The facytooltips package helps to achieve this task.
You need to create a PDF file containing the text for the tooltips (one tooltip per page). This PDF document can be produced using LaTeX; in this example I used a file (called tasktips.tex) having the following aspect:
\documentclass{article}
\usepackage{url}
\usepackage[framemethod=tikz]{mdframed}
\usepackage[createtips]{fancytooltips}
\newcommand\MyTip[2]{%
\keytip{#1}%
\begin{mdframed}[
innerlinewidth=1mm,linecolor=olive!50,
backgroundcolor=yellow!20,roundcorner=5pt,rightmargin=.25\textwidth]
#2
\end{mdframed}%
\newpage%
}
\begin{document}
\MyTip{obje1}{Continuous news coverage of 911 events presented by Worldnet (Voice of America). Please Note: This news program was recorded by the non-profit Television Archive. The video is available as a "loan" only: This means it may be streamed but not downloaded. Network URL: \url{http://www.ibb.gov}}
\MyTip{task1a}{ International Union, United Automobile Workers of America
This is from the UAW-AFL faction that split with Homer Martin from the majority UAW-CIO HD6350.A8}
\end{document}
The \MyTip command generates the tooltip text and its <key>; this <key> is to be used in the main document (the one containing the Gantt chart). The syntax for \MyTip is;
\MyTip{<key>}{<text>}
In the example, each tooltip text will be placed inside a framed colored box produced with the help of the mdframed package, but of course you can change the style according to your needs. Processing tasktips.tex (using pdflatex) you get a file tasktips.pdf containing the tooltips.
Now in your main file, all you have to do is to use the name of the PDF created in the previous step as the value for the package option filename, when loading fancytooltips:
\usepackage[filename=tasktips,mouseover,noextratext]{fancytooltips}
and then in the body of your document you use the \tooltip command:
\tooltip{<text>}{<key>}
to associate <text> with the tooltip corresponding to <key>. Here's the file with the Gantt chart and the \tooltip commands:
\documentclass[11pt,a4paper,oneside]{article}
\usepackage{fancyhdr}
\usepackage{indentfirst}
\usepackage{pgf}
\usepackage{pgfgantt}
\usepackage{pgfcalendar}
\usepackage{rotating}
\usepackage[filename=tasktips,mouseover,noextratext]{fancytooltips}
\begin{document}
\pagebreak

Some images:
and the tooltips once you hover over the text:
The downside is that you need to use AcrobatReader to properly display the tooltips.
This seems to work fine (Suggestions are welcome):
