The ambulance fell onto its side and the cruiser landed at the foot of a resident's porch. No one inside the house was injured, police said. 

Two officers were involved in the crash. One is in temporary serious condition and another is in stable condition. Two emergency medical technicians are in temporary serious condition and the patient they were transporting is in stable condition, Detroit Police Sgt. Nichole Kirkwood said Sunday. 

The pair of 2008 pumper trucks will cost $600,000 to completely rebuild, instead of the roughly $750,000 per truck the department would have to pay to buy new, Fire Chief T.J. Wiedl said.

“It’s really a huge savings for the city and, these days, I have to be cost effective,” Wiedl said. “We were really on the cutting edge when we did this with our ladder truck a few years ago, but now just about everyone is opting for this route because it’s such a substantial savings.”  

The trucks will be rebuilt from the chassis up — one will even have its chassis rebuilt — and returned as basically new vehicles by national firetruck firm Pierce Manufacturing, Wiedl said.

Although they’re 10 years old, the upgrades will make the pair the new primary vehicles in the department’s fleet of six pumper trucks and two ladder trucks.

A mid-sized aircraft, similar to a Gulfstream jet, also will be available as a prop that can be set alight so firefighters can practice extinguishing blazes and pulling people from confined spaces.

The $60 million project, a partnership between the city and Chabot-Las Positas Community College District, also will replace the Hayward Fire Department’s Station 6 at the airport near Interstate 880.

“To have the the opportunity for our region to train using our Bay Area Rapid Transit system was a real priority in the construction and design” of the center and station, fire Chief Garrett Contreras told the Planning Commission Oct. 25, when it unanimously took action to get the project built.
