A ceremony was held at LaGuardia Airport to honor Port Authority Lieutenant David Lim, who is retiring after 34 years on the job.
Lieutenant Lim was on duty in the north tower of the World Trade Center when it collapsed on September 11th.
Miraculously, he was one of 16 people that survived the collapse inside a stairwell.
His K-9 partner Sirius died in the collapse.
The gun belt Lieutenant Lim wore that day is on display at the 9/11 Memorial & Museum, along with his K-9 partner's leash.
The 9/11 attacks by Al-Qaeda terrorists killed nearly 3,000 people and caused $10 billion in property and infrastructure damage.
