Flight passengers sing happy birthday to war veteran

Video shared by Honor Flight Nevada, a non-profit organisation that honors veterans with trips and experiences, shows the passengers singing "Happy Birthday" and turning off the lights above their heads to honor the centenarian.

War veteran Charles Montanaro, who served in the merchant marines during WW2, turned 100-years-old on Sunday (January 24) and was en route to sky dive for his birthday in Arizona, Honor Flight Nevada told Reuters in a message on social media.

The organisation said the birthday singalong took place at 30,000 feet (9,144 metres).
