I would be surprised if you can loop any a/c with a high/T tail....
Pucara, C-114 Tutor, F-104, F-101, Javelin, gliders as mentioned, etc, etc beg to differ.
If you are strictly talking about large airliners or trash haulers with a t-tail you may be more accurate. Being cleared/certified for loops/aerobatics is different than being capable. Shoot the CH-53 was looped.
