It was pretty cool to see big jets 500 feet above & below me.
(American 458, traffic is a Skyhawk, 12 o'clock, 2 miles, 3500
ft--report
traffic in sight!)

Hm, is 500' enough separation for wake turbulence? The airliner was
presumably flying well below cruise speed.

That one was at 3000' on approach to LGA, going opposite to my direction.
I
don't think he was going much faster than I was :-)

Cool. Having them 500' below you is clearly ok. But 500' above you sounds
worrisome. The AIM cautions that wake turbulence can extend 1000' below an
airliner. I've never had the experience of coming closer than that, so I
don't know firsthand what it's like.
