Our reader captions:

Singapore Strait on approach.  About 10:00 AM, 4/6/12.  About an hour outside of Singapore on the way to Tokyo, a passenger had a heart attack and we had to turn around.  Only time this has ever happened to me after a half million miles flying.  This was shot on the return. Fortunately the guy seemed to be reasonably well after we landed.  Walked off under his own power.
