This from Eric Haak:
Engine 16 was involved in a 1B accident at 39th and Wallace while responding to a working fire two blocks away 6/15616. A pin-in response was requested shortly after Engine 16 notified the office that they had been involved. Squad 1 was held up on the working fire and then continued on to the accident. The last image shows the minimal damage to the engine. One member of the engine was transported to Christ Hospital.
