Back in the 90s, John Hetlinger helped fix the Hubble Space Telescope…but now, aged 82, the highlight of all his various careers as fighter pilot, engineer and more, is, apparently, to sing for Simon Cowell on America’s Got Talent. And, what a song choice! Drowning Pool’s “Bodies”. Now, to take his career to the next level, band has invited him to join them on stage for a jam at Chicago’s Open Air Festival in July. Great publicity for the band, Cowell’s TV show and a senioer wannabe rockstar and ex-fighter pilot.
