here is some light reading:
1. Cockpit voice transcript from the B-727 flight deck
http://www.airdisaster.com/cvr/psa182tr.shtml
2. NTSB Report
http://www2.ntsb.gov/ntsb/brief.asp?ev_id=40593&key=0#
3. The Audio tape of the same:
http://www.airdisaster.com/download2/psa182.shtml
And more:
http://pw2.netcom.com/~asapilot/182.html
perhaps the most telling bit is:
"Meanwhile, the 172 had unexpectedly taken up an easterly heading and continued to climb".
If anyone can consider see and avoid to be an acceptable method of routinely separating high capacity aircraft with other traffic then they are SICK.
PS. Here is a happy snap of the last seconds of 144 lives.
