statement to the 9/11 commission?
But first, Hanjour's "luck":
Three weeks before 9/11, a Cessna such as this was beyond his ability:

Yet on 9/11, without ever having before piloted a jet aircraft, Hanjour flies a 767 at 500 miles per hour, managing a 270 degree spiralling descent of 5,000 feet to plant the jet in the ground floor of the Pentagon.
A 767 cockpit:

"Aviation sources said the plane was flown with extraordinary skill, making it highly likely that a trained pilot was at the helm, possibly one of the hijackers. Someone even knew how to turn off the transponder, a move that is considerably less than obvious."

And Hanjour wasn't the only one who got "lucky" on 9/11, and 9/11 wasn't the first day for the hijackers' "luck."
Now, give Mindy Kleinberg a listen on their "luck". (Her statement is public domain, so I'm reproducing more than four paragraphs):
The Theory of Luck With regard to the 9/11 attacks, it has been said that the intelligence agencies have to be right 100% of the time and the terrorists only have to get lucky once. This explanation for the devastating attacks of September 11th, simple on its face, is wrong in its value. Because
the 9/11 terrorists were not just lucky once: they were lucky over and over again. Allow me to illustrate.
The SEC
The terrorist's lucky streak began the week before September 11th with the Securities and Exchange Commission, or SEC. The SEC, in concert with the United States intelligence agencies, has sophisticated software programs that are used in "real-time" to watch both domestic and overseas markets to seek out trends that may indicate a present or future crime. In the week prior to September 11th both the SEC and U.S. intelligence agencies ignored one major stock market indicator, one that could have yielded valuable information with regard to the September 11th attacks.
On the Chicago Board Options Exchange during the week before September 11th, put options were purchased on American and United Airlines, the two airlines involved in the attacks. The investors who placed these orders were gambling that in the short term the stock prices of both Airlines would plummet. Never before on the Chicago Exchange were such large amounts of United and American Airlines options traded. These investors netted a profit of at least $5 million after the September 11th attacks.
Interestingly, the names of the investors remain undisclosed and the $5 million remains unclaimed in the Chicago Exchange account.
Why these aberrant trades were not discovered prior to 9/11? Who were the individuals who placed these trades? Have they been investigated? Who was responsible for monitoring these activities? Have those individuals been held responsible for their inaction?
The INS
Prior to 9/11, our US intelligence agencies should have stopped the 19 terrorists from entering this country for intelligence reasons, alone. However, their failure to do so in 19 instances does not negate the luck involved for the terrorists when it comes to their visa applications and our Immigration and Naturalization Service, or INS.
With regard to the INS, the terrorists got lucky 15 individual times, because 15 of the 19 hijackers' visas should have been unquestionably denied. Most of the 19 hijackers were young, unmarried, and un-employed males. They were, in short, the "classic over-stay candidates". A seasoned former Consular officer stated in National Review magazine, "Single, idle young adults with no specific destination in the United States rarely get visas absent compelling circumstances."
Yet these 19 young single, unemployed, "classic overstay candidates still received their visas." I am holding in my hand the applications of the terrorists who killed my husband. All of these forms are incomplete and incorrect.
Some of the terrorists listed their means of support as simply "student" failing to then list the name and address of any school or institution. Others, when asked about their means of support for their stay in the US wrote "myself" and provided no further documentation. Some of the terrorists listed their destination in the US as simply "hotel" or "California" or "New York". One even listed his destination as "no".
Had the INS or State Department followed the law, at least 15 of the hijackers would have been denied visas and would not have been in the United States on September 11th, 2001.
Help us to understand how something as simple as reviewing forms for completeness could have been missed at least 15 times. How many more lucky terrorists gained unfettered access into this country? With no one being held accountable, how do know this still isn't happening?
Airline and Airport Security
On the morning of September 11th, the terrorists' luck commenced with airline and airport security. When the 19 hijackers went to purchase their tickets (with cash and/or credit cards) and to receive their boarding passes, nine were singled out and questioned through a screening process. Luckily for those nine terrorists, they passed the screening process and were allowed to continue on with their mission.
But, the terrorist's luck didn't end at the ticket counter; it also accompanied them through airport security, as well. Because how else would the hijackers get specifically contraband items such as box-cutters, pepper spray or, according to one FAA executive summary, a gun on those planes?
Finally, sadly for us, years of GAO recommendations to secure cockpit doors were ignored making it all too easy for the hijackers to gain access to the flight controls and carryout their suicide mission.
FAA and NORAD
Prior to 9/11, FAA and Department of Defense Manuals gave clear, comprehensive instructions on how to handle everything from minor emergencies to full blown hijackings.
These "protocols" were in place and were practiced regularly for a good reason--with heavily trafficked air space; airliners without radio and transponder contact are collisions and/or calamities waiting to happen.
Those protocols dictate that in the event of an emergency, the FAA is to notify NORAD. Once that notification takes place, it is then the responsibility of NORAD to scramble fighter-jets to intercept the errant plane(s).
It is a matter of routine procedure for fighter-jets to "intercept" commercial airliners in order to regain contact with the pilot. If that weren't protection enough, on September 11th, NEADS (or the North East Air Defense System dept of NORAD) was several days into a semiannual exercise known as "Vigilant Guardian". This meant that
our North East Air Defense system was fully staffed. In short, key officers were manning the operation battle center, "fighter jets were cocked, loaded, and carrying extra gas on board." Lucky for the terrorists none of this mattered on the morning of September 11th. Let me illustrate using just flight 11 as an example.
American Airline Flight 11 departed from Boston Logan Airport at 7:45 a.m. The last routine communication between ground control and the plane occurred at 8:13 a.m. Between 8:13 and 8:20 a.m. Flight 11 became unresponsive to ground control. Additionally, radar indicated that the plane had deviated from its assigned path of flight. Soon thereafter, transponder contact was lost - (although planes can still be seen on radar - even without their transponders).
Two Flight 11 airline attendants had separately called American Airlines reporting a hijacking, the presence of weapons, and the infliction of injuries on passengers and crew. At this point, it would seem abundantly clear that Flight 11 was an emergency.
Yet, according to NORAD's official timeline, NORAD was not contacted until 20 minutes later at 8:40 a.m. Tragically the fighter jets were not deployed until 8:52 a.m. -- a full 32 minutes after the loss of contact with flight 11.
Why was there a delay in the FAA notifying NORAD? Why was there a delay in NORAD scrambling fighter jets? How is this possible when NEADS was fully staffed with planes at the ready and monitoring our Northeast airspace?
Flight's 175, 77 and 93 all had this same repeat pattern of delays in notification and delays in scrambling fighter jets. Delays that are unimaginable considering a plane had, by this time, already hit the WTC
Even more baffling for us is the fact that the fighter jets were not scrambled from the closest air force bases. For example, for the flight that hit the Pentagon, the jets were scrambled from Langley Air Force in Hampton, Virginia rather than Andrews Air Force Base right outside D.C. As a result, Washington skies remained wholly unprotected on the morning of September 11th.
At 9:41 a.m. one hour and 11 minutes after the first plane was hijack confirmed by NORAD, Flight 77 crashed into the Pentagon. The fighter jets were still miles away. Why? So the hijackers luck had continued. On September 11th both the FAA and NORAD deviated from standard emergency operating procedures. Who were the people that delayed the notification? Have they been questioned? In addition, the interceptor planes or fighter jets did not fly at their maximum speed.
Had the belatedly scrambled fighter jets flown at their maximum speed of engagement, MACH-12, they would have reached NYC and the Pentagon within moments of their deployment, intercepted the hijacked airliners before they could have hit their targets, and undoubtedly saved lives.
