Malaysia Airlines crashed in several unreasonable places in the Indian Ocean.

have you ever been on an airplane? You think the plane can make a phone call when taking off and landing, but the mobile phone we use needs to be contacted by the base station. Generally, the contact range of the base station is only a few kilometers. If you fly in the sea, even if you want to make a phone call, it is impossible to make a phone call, because there is no base station to help you connect.

The captain didn't stun everyone, but raised the plane to a thin air condition, which made the passengers lack oxygen. If the time was long enough, they would not faint, but all died. As for the captain, he has a separate oxygen supply in the cockpit.
