"I'm like, what? So then we looked through a window, and that's when I grabbed my phone and recorded it."A video of the flaming debris that Davenport posted on TikTok went viral, accruing over 12 million views in a matter of days.SpaceX's Starship spun out of control shortly after its launch and exploded as it reached space. The Federal Aviation Administration closed the airspace over much of Florida after the incident and issued a temporary ground stop at several airports.The explosion comes a month after a Starship exploded during a test flight in January and rained debris down over the Caribbean,"We thought it was cool," Siler said. "We didn't think we were in any danger, and then 20 minutes later, he told us that we were going to have to go back to Punta Cana, so that was another hour and a half."Davenport said she was unnerved when, after the plane had landed back in Punta Cana to refill on gas, she overheard a flight attendant mumble, "That was too close for comfort.""Hearing that was very frightening," Davenport said.The couple eventually made it home several hours later than planned.The FAA is investigating the incident.Frontier and SpaceX did not immediately respond to a request for comment.
