A United Airlines ad across the street from ground zero that reads “You’re going to like where we land” has some New Yorkers saying the sign is insensitive because it is so close to where United Flight 175 struck the south tower on 9/11.

The MTA approved the ad and said it was a third-party vendor that put up the sign above ground at the Cortlandt Street R subway stop, directly across the street from the terror attack site.

The ad is part of a wider campaign for United, which apologized on Wednesday for another 9/11-related controversy — putting back into circulation the flight numbers from the Sept. 11 planes.

Flight 175 took off from Logan Airport in Boston, carrying 51 passengers, nine crew members and five hijackers. It hit the south tower at 9:03 a.m.

The MTA told NBC New York on Thursday that it was contacting the vendor “to remove the ad from that location as soon as possible.”

A United Airlines spokesman said the airline was not aware of the ad’s placement, and said it is part of a campaign that was launched in March.
