Amsterdam’s Schiphol airport was again hit by fuel supply problems on Friday night.

The airport authority said on Saturday it had still not determined the cause of the disruption or if it is connected to the major breakdown last month, which resulted in 180 flight cancellations.

‘Yesterday there was no fuel and we do not yet know the cause,’ the spokesman said.

The problem was made worse by the thunderstorm hanging over the airport, which halted the resumption of fuel deliveries. In the end, 10 flights were cancelled and 17 were delayed.

The TNO research institute is investigating the latest problems alongside the July crisis, fuel company AFS said.
