===How to fly over Tarrasque (3.5e or 5e)===
Tarrasque can't fly. In 3.5e, Tarasque can jump [https://www.dandwiki.com/wiki/SRD:Jump_Skill about 4 feet in the air], + 64 feet reaching from floor; hit each is [https://www.dandwiki.com/wiki/SRD:Movement,_Position,_and_Distance#Big_and_Little_Creatures_in_Combat 20 feet]. 5e Tarrasque has 20 feet Reach (with tail).

All in all, if you fly higher than maximum possible Tarrasque's reach (e.g. 88 feet for 3.5e Tarrasque; preferably higher than 95-100 feet just in case) - you can keep attacking it over and over. You would need entire wagon of arrows, but it's possible; and to do so, ''Fly'' spell is not enough (too short duration) - you need either natural flight, or mount/cohort capable of flight.

Additionally, 3.5e Tarrasque has 20ft speed, and 5e Tarrasque has 40ft speed. If you can move faster than that - you can just "kite" Tarrasque, so it would be in fire range, while not being able to reach you even if it starts to run.
