Working with NASA scientists, he coauthored a paper on error-inducing contexts in aviation. He was an air accident investigator for an NTSB inquiry into a major accident at Los Angeles International Airport, which "led to improved airline procedures and training for emergency evacuations of aircraft". Sullenberger has also been studying the psychology behind keeping an airline crew functioning during a crisis.

input: Around 2001, Chad Kroeger started "studying every piece, everything sonically, everything lyrically, everything musically, chord structure. I would dissect every single song that I would hear on the radio or every song that had ever done well on a chart and I would say, 'Why did this do well?'" Kroeger said that Nickelback's single "How You Remind Me" sold so well because it was about romantic relationships, a universal subject, and contained memorable hooks. To record their third album Silver Side Up, Nickelback collaborated with producer Rick Parashar. The album was written before the release The State and was recorded at the same studio. The album was released on Tuesday, September 11, 2001. The album peaked number 2 on the Billboard 200 with over 177,000 copies sold in its first week and peaked number 1 at the Canadian albums chart making the band's first album to do so. The single "How You Remind Me" was a number one single on the Mainstream and Modern rock charts, as well as the pop chart. It also peaked at number two on Adult Top 40 and became the Billboard Hot 100 number one single of the year for 2002. The next single was "Too Bad", which also reached number one on the Mainstream Rock Chart. The final single from the album was "Never Again", which also one hit on Mainstream Rock. In 2002, Chad Kroeger collaborated with Josey Scott on the Spider-Man theme song, "Hero". This recording also featured Tyler Connolly, Mike Kroeger, Matt Cameron, and Jeremy Taggart. In 2002, Nickelback released their first DVD Live at Home. In 2003, Nickelback released The Long Road. The album was certified 3x Platinum by the RIAA in March 2005 and it had sold 3,591,000 copies as of April 2011. It has sold over 5 million copies worldwide and in 2003 only the album sold 2 million copies worldwide. It debuted at No. 6 on the Billboard 200. This was their first album produced by Joey Moi, a former classmate of the band's. It was ranked No. 157 on Billboard's 200 Albums of the Decade. It spawned five singles. The lead single was "Someday" . The band also released "Feelin' Way Too Damn Good" as a single, which peaked at number 3 on the Mainstream Rock Charts. "Figured You Out" was also released as a single and topped the Mainstream Rock Charts for 13 consecutive weeks.

input: In mid-1983, both of Akkerman's managers came up with the idea of the guitarist reuniting with van Leer to record new music, to which Akkerman agreed. Van Leer immediately accepted the invitation, and went on to play the synthesiser on "Headbanger" on Akkerman's 1984 solo album From the Basement. After this initial collaboration, one executive at Phonogram Records suggested the pair work with producer Trevor Horn to release an album of re-recorded Focus tracks, but it was dismissed. In the following 15 months, the two wrote, rehearsed, and recorded new music with several additional musicians with engineer Theo Balijob. Their contract required the two to record as a duet, rather under the name Focus. During the recording, producer Ruud Jacobs was brought in to supervise the project due to the length of time taken to put the tracks down. Balijon claimed Jacobs cut corners and pushed for the strongest tracks to be completed quickly to save production costs, which "unintentionally increased the animosity between Jan and Thijs". In the 63 days they spent recording from April to May 1984, around 30 tracks were completed with several additional musicians. Focus was released in March 1985 by Vertigo Records which reached number 33 in the Netherlands. The pair followed the album with promotional videos and a local four-date tour. In 1988, EMI acquired the rights to the band's back catalogue and reissued their albums on compact disc for the first time. In 1990, the former line-up of van Leer, Akkerman, van der Linden, and Ruiter reunited for the first time since 1975. The four played a 40-minute set at the Americahal in Apeldoorn on 20 April that was broadcast as part of the Oud van Goud television special. It came about when producer Frans Meijer asked Akkerman to perform a gig with the group, and the fact that the guitarist's manager had not seen the band play in the 1970s, so "it was swatting two flies with one hit". The other three agreed at the opportunity, and they rehearsed for four hours in Wijchen several days prior to the concert. Ruiter said they "went very well"; van Leer said it was "fantastic". Following the concert, van Leer was keen to formally restart Focus with Akkerman, though the latter felt different though he was happy to reunite with van der Linden. On 17 May the group, minus Akkerman, mimed a performance of "House of the King" on the Service Salon television program on AVRO-TV. Originally the band were to perform "Hocus Pocus" with Akkerman, but the guitarist declined the offer made by the network, stating he reunited with Focus for Meijer and his manager. The appearance went ahead regardless. Van Leer and Akkerman shared the stage once more in 1993, performing Focus songs at the North Sea Jazz Festival. In 1999, van Leer attempted to reform Focus with Cleuver, Ruiter, and Dutch guitarist Menno Gootjes. They performed several live dates in the Netherlands, but disagreements between van Leer and Ruiter over material intended for release effectively split up the group.
