A teenager took to the skies to propose to his prom date – with a giant sign spelled out on the ground below for her to see. Jett Haifley planned the elaborate stunt with the help of his father, a light aircraft pilot. With his father at the controls, Jett and his friend Kelsey Barrett took to the skies above Three Rivers Michigan, USA. Video filmed by Jett shows them as the cruise above the picturesque countryside. And as Kelsey looks out of the window, she suddenly looks up in shock at Jett as she spots the message ‘Prom?’ written out in large letters below. Blushing with embarrassment, Kelsey eventually gives them thumbs up to Jett to accept his promposal as they double back for another look at the message hundreds of feet below.
