An Air Canada flight from Newark headed to Vancouver made an emergency landing on Friday night after abruptly dropping 26,000 feet.

Flight No. 549 left Newark Liberty just before and had a "pressurization problem with an air conditioning unit" and landed in Toronto according to a tweet from Air Canada.

“Standard procedures were followed and the aircraft descended to 10,000 feet. Emergency services were requested as a precaution only, and the aircraft landed normally without incident," spokesperson Angela Mah told CTV News.

The plane had been flying at an altitude of 34,000 feet according to the website FlightAware.com. The plane descended in 5 minutes according to a tweet from passenger Milun Tesovic. 

Tesovic tweeted that the "crew and captain did a great job" and that he had boarded another plane to complete the flight.
