PUERTO RICO, (CNN) - It's called the last flight out. The last flight to leave a tropical vacation destination for the day.
But this flight, was truly the last flight out.
The pilots aboard this Delta Airlines flight expertly navigated Hurricane Irma's strong winds and battering rains to get one last flight out of Puerto Rico on Wednesday, September 6th.
More than 1 million people in Puerto Rico are without power - nearly 70 percent of customers of Puerto Rico's Electric Power Authority. Puerto Rican Gov. Ricardo Rossello said Thursday that crews are investigating and until they know the extent of the damage, "it will be difficult to estimate how long the power outage will last."
Rossello added that ports on the island are still closed, and it's unclear when commercial flights will resume.
Schools and government offices are scheduled to reopen on Monday.
Airports in the Bahamas are shutting down with the approach of Hurricane Irma.
The government says the international airport in Nassau will close late Thursday and it urges people who plan to leave the island chain east of Florida to check with airlines for space.
Grand Bahama's airport and the less-populated island throughout the chain will close by noon Friday.
Hurricane Irma has cut a path of devastation across the northern Caribbean, leaving at least 10 dead and thousands homeless. The storm could also make a catastrophic strike on Florida.
The U.S. National Hurricane Center predicted Irma would remain at Category 4 or 5 for the next day or two as it passes just to the north of the Dominican Republic and Haiti on Thursday, nears the Turks & Caicos and parts of the Bahamas by Thursday night and skirts Cuba on Friday night into Saturday.
It will then likely head north toward Florida, where people were rushing to board up homes, fill cars with gasoline and find a route to safety.
