I was trying to be helpful staying on overtime to help dayshift wing walk Aircraft X into the hanger because they didn't have enough people to do so. The plane arrives back from the gate to the hanger. We hook up the tow bar with tug to start moving the aircraft inside. Me and Person 2 were the only wing walkers and Person 3 was on the tug. Person 3 didn't have a tail walker. So he starts moving the plane inside the hanger nose in. Well; as Person 3 is moving the plane he angles the plane to me so he clears Person 2 side because the hanger doors were not opened all the way. After Person 3 clears Person 2 wing tip on his side; he cuts the wheel so the wing tip on my side would clear. Well when he cut the wheel; he could no longer see me and if I went in his line of sight I would no longer be able to see if the wing tip clears; so Person 2 was walking to my side so he could tell how much clearance we have and that's when I crossed my arms and said cut it stop because the wing tip was going to hit the hanger door and Person 3 kept moving with the tug and hit the hanger door with the right hand wing tip and Person 2 even seen me cross my arms and he didn't say anything to the tug driver.The tug driver should have had a tail walker before tugging the aircraft and the hanger doors should have been more open but Person 3 said it was enough room  also Person 2should have told Person 3 the tug drivers I had my arms cross to stop.
