CNN —A routine part of the job for Southwest Airlines flight attendants is turning into a dangerous mess as a searing summer heat and the airline’s beverage management practices have made soda cans volatile mid-flight. There were more than 100 reports of soda cans exploding on flights in June, Southwest flight attendant union president Bill Bernal told CNN, some of which have injured flight attendants. Southwest Airlines wouldn’t comment on the number of incidents and injuries or their nature, but confirmed to CNN the issue is occurring. “Both the short term and long term fixes are actual engineered fixes that should eventually all but eradicate the exploding can issue at Southwest Airlines,” Bernal said. Soda cans are engineered and designed to handle reaching a pressure level between three to six times the can’s normal pressure, according to Biberdorf.
