(CNS) - The continued search for John Kennedy Jr, his wife Carolyn Bessette Kennedy and sister-in-law Lauren Bessette, off the coast of Martha's Vineyard, was hampered by morning haze Sunday, which grounded three helicopters and an Air National Guard C-130 airplane. Time is running out for the trio, who have now been missing longer than the 36 hours that experts say they could survive in the 68 degree water, where their single-engine plane is thought to have crashed Friday night.
"The survivability in those temperatures has been exceeded," said US Coast Guard Rear Admiral Richard Larrabee.
Appearing on NBC's Meet The Press, Larrabee said he has "not to this point" had any indication that there are any survivors to the apparent crash of Kennedy's single-engine Piper Saratoga aircraft, which he was flying Friday night from Fairfield, New Jersey to Martha's Vineyard, Massachusetts for the wedding of his cousin, Rory Elizabeth Kennedy.
Working with the Navy and Air Force, Larrabee said that he is planning to do a very thorough search that will eventually find the wreckage of the flight, if not any survivors.
John F. Kennedy Jr., 38, is the only son of former President John F. Kennedy, who was assassinated on November 22, 1963, just three days before his son's third birthday. At his father's funeral the younger Kennedy, who was affectionately known to the nation as "John-John," was photographed saluting his father's casket while viewing it with his mother Jackie, sister Caroline, and uncles Ted Kennedy and Robert Kennedy.
As one the most famous people in the world, John Kennedy Jr. spent his life in the spotlight and was dubbed by People magazine "The Sexiest Man Alive" and "America's Most Eligible Bachelor." His 1996 marriage to Carolyn Bessette coincided with the start of his journalism career as editor of George, a political magazine.
Though his father's roots are deep in Boston, John Kennedy Jr. grew up in New York City with his sister and mother, where he graduated from New York University Law School and worked for the Manhattan District Attorney's office.
Despite constant speculation that he had political or show business aspirations, Kennedy Jr. claimed that he had settled into his journalism career and was non-committal about any other ambitions.
His wife, Carolyn, 33, was a year younger than her sister Lauren, an investment banker who has an identical twin, Lisa.
