The runway reopened at 9.50am, but the incident meant several aircraft, including two Aurigny passenger planes, had to circle or divert back to the UK.
Aurigny says the incident is likely to cause delays to its schedule.
Blue Islands has arranged for an extra flight to get the passengers to Jersey.
