SOCKET TO ’EM: It was “Airplane!” for real at JFK Terminal 7 yesterday, where an unplugged scanner forced an evacuation.

BIG JOKE: Zany “Johnny” (actor Stephen Stucker) in the movie “Airplane!”

The chaos at Terminal 7 was caused by screener Alija Abdul Majed, who had manned Lane No. 1 during the morning shift with no idea his metal detector had no juice, sources said.

Amazingly, he failed to realize that alert lights never flashed once as streams of passengers filed through the dead detector, the sources said.

Majed was so clueless that he couldn’t even tell police how long the machine had been shut off or how it happened, the sources said.

“It was simply an unplugged machine — the TSA doing its best,” another source said.

Higher-ups at the Transportation Security Administration finally discovered the security boondoggle at 9:44 a.m. — leaving the Port Authority with no choice but to call for a complete evacuation of the international terminal that is home to British Airways, Cathay Pacific, United Airlines and others
