A drone flying close to Gatwick Airport led to the closure of the runway and forced five flights to be diverted for a short period of time last Sunday.
An airport spokesman said the runway had been closed for two short periods – of nine and five minutes – after the drone was sighted.
Easyjet said four of its flights were diverted, while British Airways said one aircraft was diverted to Bournemouth.
Other flights were put into holding patterns as a precaution.
The airport said: “Runway operations at Gatwick were suspended between 18:10 BST and 18:19, and again from 18:36 to 18:41, resulting in a small number of go-arounds and diverts.”
