Something found in the sky that begins with t?

It depends on where the sky begins. That is the real question. If the sky begins from the ground, then most of a tree will be in the sky, as will all the Toyotas. Perhaps the twine attaching the kite to the child will be up in the sky. If I was in a brass band and threw my tuba up in the air ....

If someone is wearing a top hat or a turban, that could be considered to be up in the air, particularly if they were flying in an aeroplane. What about a man flying a hanglider wearing trousers.

If the sky begins at the top of sky scrapers then something a little bit higher up could be a Turbo-prop aircraft.
