This is a sample of a live broadcast from 20,000 feet over the North Sea.  I was on board an RAF refuelling tanker taking part in a NATO exercise.

The piece was a logistical challenge.  My signal from the aircraft had to be picked up by a transmitter on the Isle of Wight.  That signal was then sent to another transmitter in Portishead, which converted it to a telephone signal to be bounced on to BBC Radio Gloucestershire.  I had to talk to each transmitter in turn as the chain was established.

You cannot use a mobile phone in a petrol station and the same rule applies on a refuelling tanker; no jets were allowed to refuel while I was broadcasting.  So the RAF was holding a flight of Harriers in formation while I did my broadcast.  That meant I had to tell the story clearly in a short window of time - 2' 45".
