After a transformer blew, Cleveland-Hopkins International was left without power for more than7 hours. This caused major problems, as passengers were not able to go through security or checked in for their flights.

Many travelers waited for a few hours before becoming frustrated and leaving the airport. Power was restored to the airport at 2:30 pm.

About 800 travelers were stranded Sunday morning when Cleveland-Hopkins International Airport lost power at 6:50 a.m. ET, spokeswoman Jacqueline Mayo said. Terminals went dark and air traffic ground to a halt, but the control tower, runways and taxiways remained lit by backup generators, Mayo said.
