A radar-related technical failure that led to hundreds of flights being disrupted on Wednesday was an “isolated event” with “no evidence of malign activity”, the transport secretary has said, after summoning the head of the UK air traffic control service, Nats, to account for the disruption.
Heidi Alexander said she met Martin Rolfe, the under-fire chief executive of Nats, to understand what happened and what could be done to prevent a reoccurrence in the future after more than 150 flights were cancelled and others delayed by the latest glitch.
