Recent Boeing plane crashes have been a concern to Minnesota DFL Sen. Amy Klobuchar.

The last Boeing 737 Max 8 plane crash in Ethiopia killed 150 people, including Mucaad Hussein of St. Cloud.

Klobuchar spoke to transportation and aviation government officials about federal oversight of commercial aviation Wednesday at the Senate Commerce Committee hearing.

Klobuchar said the recent Boeing plane crashes are affecting people all over the world.

"We have to make sure our planes are safe and what appears to be happening here is that there wasn't enough training and also there was some safety devices that were considered optional on the planes that weren't automatically installed," Klobuchar said.

Klobuchar said there's a big investigation going on regarding the last Boeing plane crash. She said she hopes the discussions and investigations will help improve safety in the aviation industry.

“The head of the National Transportation Safety Board told me he actually agreed with my legislation which says that the fatigue rules which are in place for passenger pilots, that means you get to sleep a certain amount of time so you’re alert, that those should also apply to cargo planes," Klobuchar said.
