Stations using WRN Broadcast’s facility in Vauxhall, South London have remained on the air, despite the nearby helicopter crash.
Two people were killed and nine injured following the incident that is believed to have occurred when a helicopter crashed into a high-rise building.
WRN said invoked its business continuity plan, which meant all services remained unaffected and on air.
Meanwhile, the nearby Digital TV Group was unaffected by the crash, though with rail and tube stations closed staff were presented with a longer walk in.
