EDIT: For an example of good planning, see how the crew from Brazil that landed prior to the crash prepared for the flight. It's in the accident docket under interviews.
Jeez. Went to look that up, and found some other tidbits. This one from the interview with the pilot's wife:
"Asked whether there was anything she could think of that could be relevant to the investigation that she had not been specifically asked about, she said that after the accident, neither she nor the copilot’s family were contacted by Trans-Pacific and
she had learned about the accident on the news about 1630 or 1700 mdt. As of the date of the interview, the company had still not initiated any contact with her. The only time she had spoken with someone from the company was when she called the owner on the day of the accident and when she called him on May 17 to obtain contact information for the copilot’s family. The owner had not provided any additional information during either of those calls."
I think this is what
@dtuuri was referring to, the interview with the FO of a Challenger that landed in front of the Lear (and they saw the crash happen):
"They flew to New York about once each year. The circle to land approach at TEB is different from what they were used to in Brazil since there they rarely had runways that were that offset. They were typically just circling to the opposite threshold. They had found an approach briefing on the internet for TEB that was very helpful. He said smaller airports in Brazil usually had an RNAV to runways to avoid circling, but not at TEB. They have done several circling approaches during various training sessions at FlightSafety, CAE and Bombardier training facilities.
Coming toward TEB, they briefed their circle to land procedure. The procedure they had was tostart the circling from TORBY and go around the Giant’s stadium to line up with runway 01.They knew it was windy and ATC liked to talk fast in the New York area. The New York area was also very busy with lots of restrictions regarding airspace, air traffic management, etc, so they briefed early and paid attention during the approach."
Man, so many people thought these pilots were substandard. Continuing to read the interviews, it turned out that they were supposed to have passengers on the accident flight, but after the BED-PHL leg, the passengers decided to drive to TEB instead!
"He said they had planned to return with the pilots, but then his brother and he looked at each other and said that they did not want to take another flight on that plane. It was not that nice of a plane, and the landing in PHL was about as scary as he had ever experienced on an airplane."
Overall, this is a fascinating read:
