A predator drone wouldn't have been able to reach it. It was really flying really high. FL600 is ~roughly at Armstrong limit, or the altitude where you absolutely need a pressurized space suit if you want to go outside, or the water in your eyeballs will boil off. The very high performance jet that intercepted the balloon didn't climb to the same altitude as the balloon, as it was over the publicly stated ceiling for that plane. Instead, it did a zoom climb and fired a missile from below as it maxed out.
