Escalators move people quickly between levels. Singapore’s malls would be unmanageable without them. Changi Airport would be chaotic.
President Trump and the First Lady had a shock at the UN General Assembly last month. The escalator they were using suddenly halted. The couple were rattled, before walking up the stationary escalator.
Trump then delivered an irate speech. His anger was not directed at America’s enemies. Instead, he called for an investigation into the elevator malfunction. The incident reminds us of the vital role of this device.
