Welcome to Airliners.Net!
I also photograph aircraft at Honolulu International. I've never been "reamed" by security, but perhaps because I've been somewhat careful at choice of locations. Lagoon Drive is a good spot, but I've personally never used it. My main location I've used is on the base of Hickam Air Force Base. I'm in the military, so I have access to it. There is a wonderful little hill that overlooks runway 8L
. Of course there is a fence, but the hill pretty much takes care of accidentally shooting it instead of the aircraft. I've spent hours in that location (which is about 100 feet from the touchdown zone) and never had a security problem. I've also photographed airplanes from the street near the old terminal and maintenance ramp, but only once and very briefly.
Unfortunately I have had little success (zero) at getting photos accepted on this wonderful web site. Quality seems to be a problem for me, even after editing the photo to get rid of digital noise. Perhaps I need a new camera. Currently I use a Sony DSC-H1 "Cyber-shot" with a separately purchased tele-photo lens. I've taken hundreds of pictures. A handful appear on myaviation.net.
