Marconi do alot of telecommunications work now days. They do some manufacturing and they might still do aerospace.
My best mate is now a head tech with Marconi after a 3 year apprentiship, he upgrades BT exchanges and does some work for the MOD which he cant talk about. Marconi make all staff do 2 weeks work and then 1 week in Coventry at school, they paid Nick back all travelling expenses for this.
