I was on V16 just off New York's JFK Airport at 6,000 feet when New York departure called.
"Mooney One Victor Sierra, say airspeed."
"One hundred seventy-five knots."
"Bonanza Five Eight Two, say speed."
"One five five."
"Can you go any faster?"
"Mooney One Victor Sierra, reduce speed to one five zero."
"No Problem. I'll slow it down for the Bonanza."
"Ouch. That's gonna leave a mark."
