The concourses at Miami International Airport were not colored red, white and blue on July 4, but instead bright lime green.
A leak in the pipe in Concourse G caused fluorescent fluid to pour from the ceiling at 9 a.m. ET, the airport said. Crews responded immediately and determined the fluid was not hazardous.
The airport reported on X that the spill had been cleaned up within an hour and a half.
“We would like to thank our passengers in Concourse G for their patience and understanding this morning,” the message said.
Greg Chin, communications director for the Miami-Dade Department of Aviation, said in a follow-up statement that the mystery solution was actually just water.
“The fluid was water from the air conditioning system with a green dye in it. If there is ever a leak, the source of it can be traced,” Chin said.
