In BCD: Bivariate Distributions via Conditional Specification

#' Aborted Flight Counts for 109 Aircrafts
#'
#' This dataset records the number of aborted flights by 109 aircrafts during two consecutive periods.
#' The counts are cross-tabulated by the number of aborted flights in each period.

#' @format A data frame with 109 rows and 2 variables:
