While cotton, from the cotton plant, and linen, from the flax plant, are both natural plant fibers (cellulose), there are many differences between them. The term Linens can colloquially refer to any household good, but this should not be confused with linen fabric.
The NTSB defines an incident as an occurrence other than an accident, associated with the operation of an aircraft, which affects or could affect the safety of operations. While many incidents do not need to be reported to the NTSB, there are serious incidents that must be reported.
Aviation Accident Database & Synopses The NTSB aviation accident database contains information from 1962 and later about civil aviation accidents and selected incidents within the United States, its territories and possessions, and in international waters. Generally, a preliminary report is available online within a few days of an accident. Factual information is added when available, and when the investigation is completed, the preliminary report is replaced with a final description of the accident and its probable cause. Full narrative descriptions may not be available for dates before 1993, cases under revision, or where NTSB did not have primary investigative responsibility.
