This was a heli lift that was happening outside our window Sunday morning for the building a block away.
The first lift, the guys on the roof almost had a real problem as the massive metal box that was being lowered started spinning. One guy tried to grab it and got thrown almost off the edge of the building. They learned in later lifts to use guide ropes 😉
Not that shocking or amazing, but still pretty cool to see a helicopter hovering 150 yds from your window.
