Talking of massive bills.
Back in my first job, used to have to download oil drilling data from drilling rigs in the North Sea (back in 1987)
Had a few ways of doing this, most involved setting up a comms link at the heady speeds of 4800, sometimes 9600 if managed to use the leased line link up to the goonhilly satellite base station.
So trying to get a comms link running with over an inmarsat link, in those days, had to pay for the satellite uplink and downlink costs, so everything was double cost - at £5.87 a minute times two plus vat
Spent 8 hours trying to get a comm link going with BP - we worked out that the bill was probably around 5 and a half grand minimum, and it never worked!
