Hawaiian Airlines says four of its aircraft were struck by lightning on Sunday and two of them were pulled off the line for maintenance.
The first strike happened at around 12:29 p.m. on Flight 19 from Sacramento to Honolulu. The next lightning strike happened at 4:10 p.m. on Flight 1121 from Hilo to Honolulu.
The third lightning strike happened at around 5 p.m. on Flight 278 from Honolulu to Kona. And the final lightning strike on Sunday happened at around 5:50 p.m. on Flight 236 from Honolulu to Kahului.
Two Boeing 717 aircraft were pulled out of service for maintenance and that cause cascading delays for the rest of Sunday, according to Hawaiian Airlines. Passenger delays were anywhere from three minutes to 2.5 hours.
"Two of our aircraft (on Sunday) sustained very minor damage from the lightning. However, as a precaution, all damages no matter how minor they are, are addressed immediately," said Huy Vo, a spokesman for Hawaiian Airlines.
Hawaiian Airlines says all of its aircraft are certified by the Federal Aviation Administration to ensure that lighting does not affect the structure or avionics of the aircraft.
