Two flight attendants were taken to Massachusetts General Hospital after a powdery substance was discovered on a JetBlue flight set to depart from Boston's Logan International Airport on Tuesday.

The flight attendants were preparing JetBlue Flight 465 for its journey to Fort Meyers, Fla., when the powder fell out of a tissue box, Massport spokesman Phil Orlandella told local station Fox 25 News.

Massport fire and rescue teams along with state police investigated the incident and found no hazardous materials present, Orlandella told Reuters.

No passengers were on board at the time and JetBlue rebooked all passengers on other flights.

The flight attendants were later released from the hospital with a clean slate. Though tests revealed that the powder was not hazardous, the jet was quarantined for further inspection.

Last month, suspicious powder was discovered on a Spirit Airlines flight from New York to Fort Lauderdale. That powder turned out to be Marijuana.
