It's a just a small token of thanks for the many Calgarians who did so much to help stranded American passengers.
The U.S. consulate presented the Calgary Airport Authority with a memorial plaque to remember the airport's help in housing thousands of American passengers who didn't have anywhere else to go.
Their homebound flights were grounded on September 11, 2001, after the attacks were made on New York City.
Consul General Laura Lochman presented a plaque to the Calgary International Airport on Friday days before the actual tenth anniversary.
Calgary received 12 diverted planes and housed 2,160 passengers on that fateful day.
