EgyptAir flight MS 804 took off from Paris bound for Cairo, Egypt with 66 passengers and crew.

Greek air traffic controllers say the plane was unresponsive as it passed over the country. The plane then plunged rapidly as it flew over the Mediterranean Sea Thursday morning local time. Egypt’s civil aviation manager says terrorism is likely.

Investigators will need to examine the wreckage and black box before much more can be known.

For more on how this investigation will unfold, Take Two spoke to Anthony Brickhouse, associate professor of aerospace and occupational safety at Embry-Riddle Aeronautical University in Daytona Beach, Florida.
