RAF is notorious for ultra low level flying. Lookup videos of their Tornados and Buccaneers doing work in Iraq.
Personally flew in an RAF Merlin in southern Iraq numerous times between Um Qasr (Bucca), Basra (Airport) and Amara in 2007... We flew UNDER every electric transmission line between the three bases. Probably between 50 and 100 every flight.
"For the price of a business class flight across the Atlantic, anyone can book a 2 hour flight in the backseat of a spitfire." Talking about a few grand, but still sort of remarkable.
