The air ambulance was called out following a crash between a tram and two cars in Fleetwood.
It landed at Freeport following the collision, which happened in Lord Street at around 12.40pm and left at least two people hurt, but was ultimately not needed.
Police said the crash involved a black Vauxhall Astra and blue Subaru Forester, with a 67-year-old man complaining of shoulder pain.
A spokeswoman for the North West Ambulance Service (NWAS) said a rapid response vehicle and ambulance were also called out, with both taking a patient to Blackpool Victoria Hospital.
Firefighters also attended the scene to release a trapped motorist, though 'additional resources' turned back after two others escaped by themselves, the service said.
An elderly man nearby fell over and also required medical attention, police said. The ambulance service was unable to say whether he was taken to hospital.
Onlookers gathered in the street to witness the crash's aftermath, while pictures taken at the scene showed some damage to the front right hand side of the Flexity tram.
The road was blocked and taped off by police, and Blackpool Transport said services one and 14 were diverted.
It reopened shortly after 4pm.
A spokesman for the Lancashire Fire and Rescue Service (LFRS) said firefighters from Fleetwood and Chorley – the base for the Urban Search and Rescue team equipped for incidents involving heavy lifting and rescue scenarios – were involved.
He said: “No-one was trapped in the cars or the tram and there were no reported injuries of occupants of the tram.”
