Does anyone else know of any hang glider pilot(s) who had US
Secret Service agents point their rifles at them while they were soaring?

In June of 1997, President Clinton visited the Birch Aquarium at Scripps
Institution of Oceanography. As a security precaution, the Secret Service asked
that the Torrey Pines Gliderport shut down all soaring operations until ~3pm,
when the President's schedule had him slated to be long gone.

A hang glider pilot friend (and co-worker at Scripps) was the first to launch at
Torrey that afternoon at about 4pm (with permission from the gliderport
authorities). Apparently, President Clinton was having a good time at the
Aquarium and tarried there much later than expected.

My pilot friend soared down south to over the Aquarium and noticed the squad of
the President's black Suburbans was still there. He thought to himself, "Oops!"
About that time, the Secret Service telephoned the gliderport and said, "Our
sharpshooters have him in their sites, so let's hope he doesn't do anything
foolish." Everyone survived the day.
