Malaysian Airlines MH370 contact lost

Jbr76:

If the aircraft crashed into sea, why hasn't there been an activation of the ELT?

• The ELT antenna was broken off in an impact
• The aircraft went in inverted
• The ELT was not working
• The touchdown was not violent enough to activate it
• The ELT was destroyed by impact forces
• The ELT is like all other ELTs and does not work underwater

This list could be only 1% of the many reasons you could use to explain why there was no signal detected.
