Default A disturbing statistic

had

not

| used did not have "real" experience and thus failed to
teach

| Lidle had a fast airplane and a CFI. But it appears they
| simply flew into box without any proper planning. Slow
| flight and steep turns, evaluation of the wind, knowing
the
| East River procedures would have saved his life. Using
the
| radio to get a clearance would have too. What will never
be
| known, were they looking at the GPS track or out the damn
| windows at the river and shore line?
|
| You can practice the East River turn anywhere, pick a road
| or river and practice a 180° turn within the confines of
the
| allotted space. You can even learn when an airspace
| violation is better than dying.

walking

airline

| accept that
|| risk, and some won't. It is better to be aware of the
| risks in flying

don't
| apply to

||
|| The 2005 Nall report shows a total 1413 GA accidents,
| fatal and
|| non-fatal, or 6.22 accidents/100,000 flight hours.
| Applying the

|| 41.47 accidents per 100 million miles.
||
|| According to NHTSA, there were an estimated 6,159,000

|| motor vehicle accidents in 2005, of which there were
| 43,443
|| fatalities. Dividing the 43,443 by the 2,965 billion

| General Aviation
|| aircraft. Since you have to have had some kind of
| accident in order

||
|| The problem is that airplanes go so much faster. If you
| do have an
|| accident at 150 mph, you're more likely to die as a

|| crashworthy than automobiles. One might speculate what
| the fatality

| at 150 mph,
|| even if such speeds didn't bring with it an even higher
| accident rate.
|| Examining automotive fatality and accident rates in
| places like
|| Germany, where in some parts high speed driving is
| commonplace, might
|| be instructive. Only 0.7% of those automobile accidents
| were fatal
|| while 20% of the aircraft accidents were fatal.
| Airplanes don't crash
|| as often, but when they do, it's bad.
||
|| Perhaps one conclusion is that more attention should be
