Friday's launch was part of what Esa calls the Vega Research and Technology Accompaniment (Verta) programme - a sequence of flights intended to demonstrate the rocket's capabilities whilst at the same time moving it towards full commercial service.
Ofcom tested the programme and found that for one sequence during Cole's performance, lasting just over five and a half seconds in total, nearly four seconds of non-compliant material was found.
