A passenger aircraft made an emergency landing at Norwich Airport after the pilot reported an electrical fault and fumes in the cockpit.
Ten fire engines were sent to the airport to meet the diverted KLM flight from Manchester to Amsterdam Schiphol.
The Boeing 737 with 114 passengers on board made a normal landing, airport director Andrew Bell said.
Passengers disembarked safely and checks were then made to the aircraft.
Eighty of the passengers were put up in hotels overnight.
Mr Bell said a full emergency was declared and the plane landed just after 14:30 BST.
A KLM spokesman said the plane had made a "precautionary landing because of unidentified fumes" and was being repaired.
The aircraft left for Amsterdam on Tuesday evening and would return to service the next day, he said.
