Investigators and forensics teams descended on the site of the Malaysia Airlines crash in Ukraine Thursday and Friday in an attempt to recover the remains of an estimated 80 passengers who are still unaccounted for. The teams returned after more than a week of fighting between Ukrainian troops and pro-Russian separatists, which prevented investigators from entering the site. So far, at least 200 of the 298 passengers aboard MH17 have been recovered after the airline was shot down by a ground-to-air missile on July 17.
