In what looks like no more than an overblown storm in a teacup, a US private transatlantic telecommunications start-up, Pan American Satellite Corp is complaining that neither Mercury Communications nor British Telecom will negotiate with it on linking a UK earthstation to their domestic networks, and is asking the US to oppose Mercury’s parent Cable & Wireless Plc expanding in the US by offering international services in a full page advertisement of its letter to President Reagan that appeared in yesterday’s Financial Times – but Mercury says that it has no objection to linking its network with that of Pan American – it simply has not yet received a detailed proposition from the company, whose satellite is due to go up on Ariane in March.
