Big bro gives little brother with Williams syndrome the gift of flight

This might be the cutest thing you see all week.

The video, which went viral earlier this week shows big brother Mikey taking Robbie up for his first plane ride.

Robbie has Williams Syndrome, a rare genetic disorder which in some cases causes a sensitivity to certain frequencies of sound.

Twenty-year-old Mikey told Anton Savage at TodayFM, an Irish radio station, that he was nervous that the engine might frighten Robbie, who has wanted to fly for years.

Robbie’s older brother and father are both licenced pilots, and both flew first at age 5.

Luckily, the brave little guy was happy as a lark, giggling and joking with his big brother throughout the 10-minute flight.
