Just ‘plane’ skeery – NYC air-traffic controllers alleged twice as accident-prone as U.S. average.

The figures are plane terrifying — especially for New York fliers.

Air-traffic controllers monitoring the Big Apple's choked airspace rack up mistakes at more than twice the national rate, an exclusive Post analysis of government data found.

Controllers in the New York City area make one error per 40,000 flight operations, Federal Aviation Administration figures show. That's more than double the national average of one error per 84,000 flight operations.

It also is a higher rate than their counterparts in other big cities. For example, Atlanta controllers err in one out of 56,000 operations, while Chicago controllers make mistakes in one out of every 53,000 operations.
