Hi there!
Not sure about what was you are asking about, so I will give you two answers:
* You cannot use a flying machine to land your builder (buildingmaster) on a tile.
* However, you can use a flying machine to land any meeple on a tile with a builder (from your or any other player). Actually, your meeple can land on any valid feature no matter if occupied or not (by a meeple, a builder or any other figure).
Hope this helps.
