helicopter around park and otis

[c_death]

I woke up at 6:30 ish, went outside for a smoke and saw a helicopter hover right above Park and San Jose for a good few minutes, it moved over to just south of San Jose (more towards Otis) and more west and actually dipped lower and hovered (seriously I thought it was trying to land on top of a roof)

a friend twittered about a half hour later with the same thing... woke up at 6:30 to sound of helicopter...

so what is up?
