In an effort to assist I posted the following on the Sky News feedback.
I was fascinated by a report on your news last night describing a forced landing by a single engined aircraft at Sorrento, Victoria.
The report indicated that there were four people on board the Cessna, it is in fact a Piper, but lets not worry about the detail
My attention was drawn the bit where your reporter described how the pilot could jettison the wings to avoid a fuel fire.
As a licensed pilot I thought that you might be interested in how this is done.
The best method is to fly very low between two trees spaced at a smaller interval than the wing span. That does it every time
