The Degree of the Chart Ruler is Venus and Venus is in one of the Degrees which rule: "AVIATORS"
Venus is in the 10th House which Mundanely rules the EVENT or Events the Mundane Chart is presenting. Venus is alone in this House. Venus usually indicates people connected to Art & Entertainment or Young Girls. But; it can also indicate a "Valuable Resource, Asset, or Person".
Venus is Retrograde, so; putting all that together, gives us:
A Valuable Aviator ... with some "inability" (RX) to function or "hampered in some way"
The Vertex is in the 8th which it shares with the Moon (Midheaven Ruler). The Vertex is a "Fated Aspect"... something which will be encountered. How one Reacts to that Encounter is still one's own Choice.
This Vertex tells a story of its own through its Decanate & Degree Meanings .... as follows:
 Degree Meaning: Someone with knowledge of "Inner Secrets".
 Decanate Meaning: "An assault ... an Inside Job" on a Leader by his own People".
AND WHAT ABOUT THE MOON which shares the 8th House of Death & Endings rules the Midheaven .... the Event taking place?:
Venus "holds the 10th House" as its Ruler; but the MIDHEAVEN is a "separate entity" and must be taken into account. It rules & indicates the "EVENT" the chart is describing.
The Midheaven's ruler is the Moon and it is in the 8th House of Death.
The Moon shares this house with the Vertex. The Vertex indicates "Fated Aspects".
So: taken together: "A Fated Death Event"
NOTE: There are said to be "2" kinds of "Fate":
 - The First type of Fate is said to be "Destiny" which is also said to be determined by one's Character ... and thus can be affected by the individual(s) involved.
 - The Second type of Fate is said to be un-alterable except by "God". This type of Fate is said to be "Something the Individual Must Experience or Encounter"; yet still has Choice in how they react to that encounter.
The Moon is also in an AVIATOR DEGREE
The Moon's degree meaning speaks of:
Experiment & Research & Thoroughness
Speaking out or Publishing
The Moon's decanate meaning?
"A MYSTERY TO BE SOLVED"

A Few Small Points

There have been comments made regarding the safety harness in Fossetts plane having been "unscrewed". These comments have not yet been confirmed ... but; how that could happen is unexplained.
Is it possible that Fossett survived the accident and died on the way to get help.... or.... was he "helped" on his way to die?
What does the chart indicate when it says that Fossett was under assault by his own people? Did this refer to a business deal that he was fighting ... and perhaps he had gone on this particular flight to "think things out". Or was his flight cut short due to treachery from his own "people" who thought they could get a better "deal" if Fossett was out of the way?
Or: was Fossett "on to something" that others did not want known... something he might have been prepared to "speak out about"?
Did Someone or Something want to STOP Stephen Fossett? And if so ... Stop him from What?
Fossett was himself a world-renowned adventurer. He set 115, flying & sailing records; including being the first to fly around the Earth alone without refueling. He was also a wealthy financial broker who had swum the English Channel and climbed Mount Kilimanjaro.
Fossett had taken off from the Flying M Ranch (Yerrington, Nevada), owned by his friend Barron Hilton (hotel mogul) in a Bellanca Super Decathlon acrobatics plane. When initially, neither he nor his remains could be located; he was declared "dead" on Feb 15th, 2008.
