What would you tell the head of NASA?

[Safety4All]

Maybe it is better to not judge the study by its cover. It is not too difficult to get some meaningful numbers from the data that can be found here:
http://www.nasa.gov/news/reports/NAOMS.html

The most interesting part (for me) are the "Redacted Air Carrier Survey Responses" which list safety-related events during some 2.5 million flight hours.

Using that number the following can be deducted about many safety-related events, for example (always in the period April 2001 till December 2004):

1. On average an air carrier pilot had to perform an evasive action about once every 700 flight hours to avoid an imminent in-flight collision with another aircraft that was never closer than 500 feet including evasive action in response to a TCAS advisory.
2. The same pilot experienced less than 500 feet of separation from another aircraft while both aircraft were airborne about once every 1600 flight hours.
3. Our pilot was unable to communicate with A.T.C. in a time-critical situation because of frequency congestion about once every 110 flight hours (half of which while airborne in the terminal area).

And the list goes on. The data was obtained from what pilots were able to recall from memory during a 30-minute telephone interview about safety-related events they experienced during the most recent 90 days before the interview.

In other words, the real numbers today are probably even more disturbing...
