Pray for MH 370

MH 370 has been missing for six days now and is still not found despite all the efforts from 9 countries. The Plane mysteriously vanished from radar and is never seen again.
It's really scary! That's why I don't enjoy flying... Pray for the 229 people on board including the crew members  
Thank you to all the countries that offer help. I wish I can help in a way because meeting the end on the plane is the worst way to go! I can only pray for them and pray that a miracle may happen. Maybe they got stranded on an island. 
If it did really went down to sea, my theory is that there was incident in the plane's mechanical system that release gas (i think, I'm no airplane engineer) that causes the crew to fall asleep. After that, the plane simply just fall down to the ocean after floating on air for a few hours. This was my guess the first time I read about this. Actually, there was an episode in 'Air crash investigation' that covered this and maybe that's why there were't any distress call. I wish I'm wrong and hope that they're trapped on an Island somewhere.
