WASHINGTON (CNN) -- For years, retired Air Force Col. John Leech has had no desire to return to the Pentagon. Retired Col. John Leech narrowly escaped death at the Pentagon on September 11, 2001. Leech narrowly escaped death September 11, 2001, when a hijacked American Airlines jetliner hit the building. He will attend Thursday's dedication of the Pentagon memorial honoring the 184 people killed in the terror attack. In an earlier visit to the memorial, Leech left a note for his friend Navy Capt. Jack Punches: "Thanks Jack for serving and dying for our nation." Leech could barely contain his sadness recently as he watched a Department of Defense videotape showing the burned interior of the area in the building where he was that fateful morning. "Wow. My God. ... It makes you weak in the knees to see these pictures," Leech said. Leech, 54, recently took CNN into an office not far from the conference room where he was that morning. He has avoided touring the building since the attack but finally decided he was ready to "re-engage" with the past. In 2001, Leech was working as a Defense Department liaison officer to the White House Drug Policy office. He worked primarily out of the White House but attended meetings at the Pentagon every Tuesday and Thursday morning.  Watch as he returns to the crash site » . As he walked the now-renovated halls where he spent the morning of September 11, he recalled the horror of the day. The shock, he said, was indescribable. "It hit with such force. I had never experienced anything like it in my life. It rattled you right down to the bone," Leech said. Flight 77 slammed into the west wall of the Pentagon at 9:37 a.m. ET. Among the 184 people killed in the building and on the plane were a 3-year-old girl and a 71-year-old retired Navy captain, the youngest and oldest victims, who were both passengers on Flight 77.  A closer look at the new Pentagon memorial » . Several people were killed or severely burned not far from where Leech took cover. He remembers people screaming, "bloodcurdling screams." "I was so lucky. ... It was almost like we were in a protective cocoon," Leech recalled. "I mean, I inhaled a lot of jet fuel vapors, and I got dusted up, but that was the extent of my injuries." The married father of a 26-year-old woman remembers snaking his way outside the burning building, where in a stupor he noticed a comb that appeared to belong to a small child. "A little girl's comb that was untouched. It was not scorched; it didn't have smut on it," Leech remembered. "It was a pristine red comb sitting off the side, and next to it was a tattered suitcase, and I can remember looking at that and thinking, who did that belong to? What little girl did that belong to?" Leech served 28 years in the military and now works for the Department of Homeland Security but hopes to return one day to the Defense Department. Seven years after that horrible day, Leech visited the chapel at the new Pentagon Memorial, a two-acre park, which opens to the public Thursday. It was built at the spot where Flight 77 plowed into the Pentagon and will be open 24 hours a day, seven days a week. Thumbing through a condolence book in the chapel, he found the friend whom he was with that day, Navy Capt. Jack Punches. He wrote, "Thanks Jack for serving and dying for our nation -- John Leech." "I've avoided ... anything to do with 9/11, so it feels good to be here," he said. "I mean, a lot happened that day. A lot of good people died. A lot of very good people."

Washington (CNN) -- Colleagues of Sen. Robert Byrd of West Virginia mourned his death as family and friends planned his funeral. Byrd, the longest-serving member of the U.S. Congress, died Monday at the age of 92. Under West Virginia law, the state's popular two-term Democratic governor, Joe Manchin, has the power to appoint Byrd's successor. Manchin is expected to name a fellow member of his party to succeed Byrd, who was also a Democrat, thereby keeping a total of 59 Democrats in the Senate. There are questions, however, regarding exactly how long Byrd's appointed successor can serve before another election is held. West Virginia law says that if a Senate vacancy is created within two and a half years of the end of a term, the appointed successor will automatically serve out the remainder of the term. If not, a special election is required. Byrd's current term is scheduled to end on January 3, 2013. The two and a half year mark will be reached on Saturday, July 3. West Virginia law fails, however, to state exactly when a vacancy occurs. Whether the vacancy is considered to have been created at the moment of Byrd's death, or when the Senate informs state officials of the vacancy, or when Manchin declares the seat vacant will be crucial. West Virginia -- a traditional Democratic stronghold -- has been increasingly competitive for the Republicans. John McCain easily defeated Barack Obama in West Virginia in the 2008 presidential election. Neither Manchin nor the Democratic-led Senate have made any official declarations yet. As question swirl around the timing of the next election for Byrd's seat, numerous political leaders have been issuing statements in remembrance of the nine-term senator: . -- President Barack Obama . "The people of West Virginia have lost a true champion, the United States Senate has lost a venerable institution, and America has lost a voice of principle and reason with the passing of Robert C. Byrd. Senator Byrd's story was uniquely American. He was born into wrenching poverty, but educated himself to become an authoritative scholar, respected leader, and unparalleled champion of our Constitution. He scaled the summit of power, but his mind never strayed from the people of his beloved West Virginia. He had the courage to stand firm in his principles, but also the courage to change over time." -- Gov. Joe Manchin, D-West Virginia . "Sen. Byrd was a fearless fighter for the constitution, his beloved state and its great people. He made a significant mark as a member of Congress in both our state's and nation's history. His accomplishments and contributions will define history for eternity." -- Sen. Jay Rockefeller, D-West Virginia . "It has been my greatest privilege to serve with Robert C. Byrd in the United States Senate. I looked up to him, I fought next to him, and I am deeply saddened that he is gone. He leaves a void that simply can never be filled. But I am lifted by the knowledge of his deep and abiding faith in God, I have joy in the thought of him reunited with his dear (late wife) Erma, and I am proud knowing that his moving life story and legacy of service and love for West Virginia will live on. Senator Byrd came from humble beginnings in the southern coalfields, was raised by hard-working West Virginians, and triumphantly rose to the heights of power in America. But he never forgot where he came from nor who he represented, and he never abused that power for his own gain." -- Senate Majority Leader Harry Reid, D-Nevada . "By virtue of his endurance, Robert Byrd knew and worked with many of the greats of the United States Senate. Because of his enduring virtue, he will be remembered as one of them. Senator Byrd dedicated every single day of his Senate service to strengthening the institution, state and republic that he loved so dearly. There will never be another like him." --Senate Minority Leader Mitch McConnell, R-Kentucky . "Sen. Byrd combined a devotion to the U.S. Constitution with a deep learning of history to defend the interests of his state and the traditions of the Senate. We will remember him for his fighter's spirit, his abiding faith, and for the many times he recalled the Senate to its purposes. ... We are glad to know that Senator Byrd and his beloved Erma are reunited. We extend our deepest sympathies to the entire Byrd family." --Sen. Patrick Leahy, D-Vermont . "No senator came to care more about the Constitution or to be a more effective defender of our constitutional government than the senior senator from West Virginia. He was a senator's senator. ... I know him as a mentor and a friend. I was honored to stand with him and fight against assaults on the Constitution and against an unnecessary and costly war in Iraq. He was a self-educated man who learned much throughout his life and had much to teach us all. He was a symbol of West Virginia, he was an outstanding senator, and he was extraordinary American." --Sen. Jeff Sessions, R-Alabama . "It is a sad day for all of us. There was no one who loved the institution of the Senate more, and no one who was a better student of it." CNN's Ted Barrett, Alan Silverleib, and Paul Steinhauser contributed to this report.

This is the second part of a two part series on the best used luxury cars. (AOL Autos)  -- Recently, Consumer Reports magazine issued its list of best and worst used cars, and divvied them up by price range. The Porsche 911 has several versions, but all have been annointed with the "supercar" appellation. Using CR's recommendations as a guideline, here is a list of some of the best used luxury cars currently on the market in the $30,000+ price range: . 2007 Acura MDX . The newer MDX is classified as a crossover SUV, but it's a deluxe version. It was all-new in '07, and was built on a proper platform -- as opposed to being adapated from the Accord passenger-car platform. It also came in three flavors: Base, Technology and Sport Packages, and all three were powered by a 3.7-liter 300-hp V6. The voice-activated navigation system is a nifty feature, as it comes with rearview camera and AcuraLink satellite communications with real-time traffic data. AOL Autos: Used Acura . 2007 BMW 328i sedan . The 328i is another sleek, finely-tuned and beautifully-designed driving machine, offering sporty performance and Euro-style luxury. It is widely considered to be the definitive "sports sedan." The '07 328i was propelled by a 3.0-liter 230-hp inline six-cylinder engine, which you can find mated to either a six-speed manual or six-speed automatic transmission. Consumer Reports also recommended the 3-Series coupe and convertible that joined BMW's model line-up in '07.  AOL Autos: Used BMW . 2004 BMW M3 . The M3 is the top-of-the-line, high-performance-tuned version of the 3-series coupe. Performance power, therefore, is much higher than the other 3-Series editions. It came as a coupe or convertible, and churned out 333 horses. The M3 is often favorably compared to the Porsche 911 when it comes to quick acceleration, crisp braking and taking tough corners at brisk speeds without breaking a sweat. 2007 Infiniti FX35 . Well, the marketplace surely is not lacking for luxury crossovers. Here is yet another one that appeals to luxury buyers with its balance of SUV-type spaciousness, pampering amenities, deft handling and burly engine muscle. For '07, the FX35 was a two-wheel-drive vehicle powered by a 280-hp 3.5-liter V6 and a five-speed automatic transmission. AOL Autos: Used Infiniti . 2006 & 2007 Infiniti M . Infiniti's M series is another winner, which seamlessly synergizes sleek styling, aggressive engine performance and a bevy of luxo-line amenities. It comes in both the M-35 and M-45. During the last used-model year, '07, the primary distinction between the two was that the M35 was powered by a V6 that kicked out 275 horses, while the M45 muscled up to a 325-hp V8. Luxury features included standard leather seats with heating and ventilation, and optional 10-way power adjustments for the driver's seat. Lexus . Just like in the $24,000-to-$30,000 category, Consumer Reports recommended a slew of world-beating used Lexus models in this segment: the '06-'07 6-cylinder GS RWD; the '07 GS450h Hybrid; '05-'07 GX; '07 IS; '04-'07 LS; '03-'06 LX and '06-'07 RX. AOL Autos: Used Lexus . Lexus has placed No 1 in the JD Power Dependability Survey every year for the last 12 years - until '07, when another carmaker, Buick, finally tied them for first. Porsche 911 (various years) Consumer Reports included the '98 911 in the $24,000 to $30,000 category. Here, the model years get more recent as the price range climbs. The 911 went through some changes over this time period, of course, but all have been anointed with the "supercar" appellation. AOL Autos: Used Porsche . And by the latest recommended used-model year, the '07, you could choose among various styles and engine sizes, including the Carrera, with its 3.6-L 325-hp flat-six plant; the Carrera S and S Cabriolet, with the 3.8-L 355 hp V6; the 911 Turbo, with twin-turbocharged 480 hp six-cylinder engine; and the GT3 track model, powered by a high-revving 415-hp six-cylinder engine.
