Well, as we saw with the recent BA
777 crash at LHR
, you can certainly take crash photos well after the crash has occurred. The question is, SHOULD you take pictures of a crash? I don't know the answer to that question. I have only photographed one accident, a Learjet that crashed into the water on final, killing two crewmembers. I went out and took some shots as the aircraft was being pulled out of the water, and right by me were a whole slew of news media doing the same. I have a degree in journalism, and I justifty taking shots of this grisly scene as capturing a newsworthy event. But in some respects, I wish I'd kept my camera in its bag that day.
