A similar chopper of shree airlines crashed at Everest base camp in June 2005 when it had gone to bring back the nepal rotary everest expedition team members. Fortunately, it happened while it was trying to balance its tail during landing, which hit one side of the mountain and all aboard were able to get out on time. no explosion took place, but the chopper remains in the EBC till this date...i believe. So, this is probably not the first time that shree airline chopper has run into problem. i just hope that the investigation team formed under the chairmanship of hon. judge Keshari pandit will uncover the truth behind the incidents and take necessary actions to prevent any such great mishaps in future and punish the culprits - if any. This much the departed souls deserve! Om shanti!
