The space shuttle Enterprise is tentatively scheduled to arrive in New York City on Friday.
The shuttle had been scheduled to arrive earlier in the week but NASA had it pushed back because of bad weather.
The Enterprise is being brought to the city where it has a new permanent home waiting at the Intrepid Sea, Air and Space Museum.
The museum is at a decommissioned aircraft carrier moored off Manhattan. It's been making room for the shuttle on its flight deck.
