However, the weather was officially listed as "visual meteorological conditions" (VMC), which allowed Kennedy to fly under Visual Flight Rules (VFR) rather than Instrument Flight Rules (IFR), as he lacked an instrument rating . However, the visibility was very poor in Essex County, New Jersey, and airports along Kennedy's flight path reported visibilities between 5 and 8 miles with haze and a few clouds . Some pilots flying similar routes as Kennedy on the night of the accident reported no visual horizon over water because of haze . Also, the NTSB reported on one pilot who cancelled a similar flight that evening due to "poor" weather . The conditions near the crash site were: "Clear skies at or below 12,000 feet; visibility 10 miles". </P>
