The crash of Malaysia Airlines Flight 17 in Ukraine has many people thinking about the disappearance and presumed crash of another Malaysia Airlines plane -- Flight 370 -- in March.
While video is showing the smoke from presumed crash location of MH 17, no wreckage has been found yet for MH 370.
Here's what the planes had in common:
Both flights were on Boeing 777s, according to ABC News.
Both flights were connected to Kuala Lumpur. MH 17 was flying from Amsterdam to Kuala Lumpur when it went down over the Ukraine on Thursday. MH370 left Kuala Lumpur for Beijing when it disappeared on March 8. Air traffic controllers lost contact with MH370 over the waters between Malaysia and Vietnam.
MH17 had 295 passengers and crew members on board. MH370 had 239 passengers and crew aboard.
The Russian news agency Interfax says MH17 was shot down.
Investigators don't know what brought down MH 370. Theories range from mechanical failure to hijacking to pilot murder-suicide, but without finding the plane or its flight data recorders officials have been unable to say with any certainty what happened on board.
