Otakon celebrates 20 years of anime fandom in the U.S.

Nonetheless, there have been some hiccups. A train accident in 2001 released chemicals that triggered pressures beneath the city’s streets, blowing open several manhole covers around the convention center. In 2010, the center’s fire alarms sounded by mistake, causing the evacuation of over 20,000 attendees during peak hours. Both events were handled with grace, and the convention has had no incidents of serious crime or assault.

hiccupは「しゃっくり」が最初に浮かびますが、他に「〔…の〕（短時間の）中断、故障；（一時的な）小さな支障」という意味もあります。（『ジーニアス英和辞典　第４版』大修館書店）
