Two Americans have ignited a race to build the world's tallest flagpoles - here are some of their record-breaking designs
Tajikistan, Turkmenistan, Jordan, and the UAE have all held the record at one point - locked in a bizarre nationalist rivalry pushing flagpoles ever-taller.
Two Americans have profited handsomely from this competition. Their company, Trident Support, has been responsible for five of the last six record-breaking flagpoles built over the last 10 years.
Last year, I spoke to Trident founders David Chambers and Marc Summers, to find out how they managed to build and command a market for flagpoles that defy gravity.
