re: Francis Scott Key Bridge in Baltimore has collapsed - container ship wrecked into it

I dont understand how that is possible. Time to close the breaker on an emergency generator which is generally a self contained high speed unit is like 15 seconds from blackout at best. The medium speeds I've messed with took about 10 seconds to start. Blows my mind that a cross head engine could be clutched in in less than a minute from start signal.
