Mutallab was described by "The New York Times" as "among Nigeria's richest and most prominent men," by "The Telegraph" as being "one of Nigeria's most prominent bankers", and by "The Guardian" as being "one of the country's most respected businessmen".  Mutallab's son, Umar Farouk Abdulmutallab, is a student who attempted to detonate plastic explosives aboard Northwest Airlines Flight 253 on 25 December 2009.

1993 Bombay bombings: The 1993 Bombay bombings were a series of 12 bomb explosions that took place in Mumbai, India, then known as Bombay, on 12 March 1993.  The coordinated attacks, carried out in revenge for earlier riots that killed many people, were the most destructive bomb explosions in Indian history.  This was first of its kind serial-bomb-blasts across the world.  The single-day attacks resulted in 257 fatalities and 717 injuries.  Thirteen blasts were announced by the then Chief Minister of Maharashtra Sharad Pawar, the fictitious one in a Muslim quarter of the city, to prevent the events from taking on a communal hue.

Sexuality after spinal cord injury: Although spinal cord injury (SCI) often causes sexual dysfunction, many people with SCI are able to have satisfying sex lives.  Physical limitations acquired from SCI affect sexual function and sexuality in broader areas, which in turn has important effects on quality of life.  Damage to the spinal cord impairs its ability to transmit messages between the brain and parts of the body below the level of the lesion.  This results in lost or reduced sensation and muscle motion, and affects orgasm, erection, ejaculation, and vaginal lubrication.  More indirect causes of sexual dysfunction include pain, weakness, and side effects of medications.  Psycho-social causes include depression and altered self-image.  Many people with SCI have satisfying sex lives, and many experience sexual arousal and orgasm.  People with SCI employ a variety of adaptations to help carry on their sex lives healthily, by focusing on different areas of the body and types of sexual acts.  Neural plasticity may account for increases in sensitivity in parts of the body that have not lost sensation, so people often find newly sensitive erotic areas of the skin in erogenous zones or near borders between areas of preserved and lost sensation.

Northwest Airlines Flight 253: Northwest Airlines Flight 253 was an international passenger flight from Amsterdam Airport Schiphol in Haarlemmermeer, Netherlands, to Detroit Metropolitan Wayne County Airport in Romulus, Michigan, United States.  The flight was the target of a failed al-Qaeda bombing attempt on Christmas Day, December 25, 2009, in which a passenger tried to set off plastic explosives sewn to his underwear.  There were 290 people on board the aircraft—an Airbus A330-323E operated by Northwest Airlines, which had merged with Delta Air Lines the year before.  Had the attempt succeeded, it would have surpassed American Airlines Flight 191 as the deadliest aviation occurrence on U.S. soil and tied Iran Air Flight 655 as the eighth-deadliest of all time.  The incident was also the second in 2009 involving an Airbus A330, after the crash of Air France Flight 447 on June 1.  This was also the final accident/incident involving Northwest Airlines as it closed down a month later when it merged with Delta Air Lines.

2002 El Ayyat railway accident: The El Ayyat train disaster happened at 02:00 on the morning of 20 February 2002 in an eleven-carriage passenger train travelling from Cairo to Luxor.  A cooking gas cylinder exploded in the fifth carriage, creating a fire which engulfed seven third-class carriages, reducing them almost to cinders.  The initial number of dead given by officials at the time was 383, all Egyptians.  However, considering that seven carriages were burnt to the ground, and each carriage was packed with at least double the maximum carrying capacity of 150, this number is considered by many people to be a great underestimate.  The dubious nature of the given death toll lies with the absence of a full passenger list; accounting for those missing was almost impossible at the time.  In addition, the fire was so intense and the carriages so badly burned that many corpses had been reduced to ash.  As there was no means of communication between the driver and the rear carriages, the driver did not know of the fire until about two hours after it had begun, resulting in many people, attempting to flee from the overcrowded carriages, jumping to their death.  Some important Egyptians have commentated that the official number of 383 dead is grossly inaccurate and was an attempt to lessen the damage done to the reputation of the government.  Many people consider a number of about 1000 deaths to be more accurate.

Niles Canyon ghost: The Niles Canyon ghost story is the Northern California variation on the vanishing hitchhiker archetype.  There are many different variations of this story depending on whom you ask.  All stories include a girl being involved in some sort of motorized vehicle accident on February 26 (year often changed).  One variation of the story includes a girl being involved in a car crash on Niles Canyon road (off the 680 freeway in Sunol, California) on the way to her prom.  The girl died on impact and to this day is said to haunt Niles Canyon road every February 26.  The tale of the haunting goes that people traveling along Niles Canyon road (now Highway 84) on the night of February 26 will see a normal-looking high school-aged girl walking along the road in a prom dress (many people have said it is white).  People traveling along the road (mostly those traveling alone) have said to have stopped and offered the girl a ride.  She accepts the ride, giving the driver an address across the bridge (either Dumbarton or Bay Bridge depending on the storyteller).  Once the driver gets to the beginning of the bridge, the girl will disappear.  Sometimes people have gone to the address to find that a girl many years ago matching that description once lived there.  Today, many people will travel along this treacherous pitch black road in the hopes of catching a glimpse of the Niles Canyon ghost.
