A graduate student in a University of Wisconsin-Madison engineering lab heard a whoosh and saw flames Monday morning during a routine test of an engine, according to a release. Emergency crews were called around 8:45 a.m. to the Engineering Research Building in the 1500 block of Engineering Drive, officials said. During full-throttle tests of an engine, the grad student heard the whoosh and saw flames extending from one side of the engine, according to the release. The building’s fire alarm system activated when 4-foot flames climbed toward the ceiling.
