Families of some of the 346 people killed in two crashes of Boeing 737 Max airplanes on Wednesday gave emotional testimony to a congressional committee investigating the now grounded planes.

The Federal Aviation Administration found a new problem in Boeing's Max plane last month, so it will likely be several more months before the troubled plane is certified to fly passengers again.

Southwest, American and United Airlines have already pulled the aircraft from their schedules through Labor Day weekend. Two of the planes crashed within five months, killing hundreds of people.

"Sully" Sullenberger, who landed a plane on the Hudson River in 2009, says he understands how the pilots of two jets that crashed would have been confused as they struggled to control the aircraft.

Boeing got a big vote of confidence in its troubled 737 Max. A European airlines group has inked a deal to buy 200 of the jets. But the troubles are far from over.

Airlines say a record number of people will fly this summer so TSA is working to keep checkpoint lines moving. But the travel industry worries a plan to move agents to border security could increase wait times.

More than 300 of the planes, including some of the grounded Max versions, may have flawed parts on their wings. The problem is not considered something that could lead to a crash.

The head of the Federal Aviation Administration hinted it could recertify the plane to fly passengers again by as soon as late June, but he would not commit to a timetable.

Global aviation safety officials are meeting in Fort Worth to discuss how they will certify Boeing's 737 Max as airworthy and how soon the troubled plane can fly again.

The grounding of one of Boeing's most popular planes has Southwest, American and United canceling some summer flights — fares may go up for travelers affected.

Boeing says it has completed development of a software fix for its trouble 737 Max planes, addressing a flight control system that investigators have implicated in two recent deadly crashes.

A preliminary report into the deadly Ethiopian Airlines crash suggests the plane's pilots followed all suggested procedures. The report opens a new round of questions into the 737 Max aircraft.

Last week, Boeing said software fixes for its troubled 737 Max airplanes were finished and ready to go. But now the company says more time is needed to make sure the fixes are done right.

The company is still producing about 50 737 Max planes per month. This week, it unveiled software fixes and other improvements for the fleet as it tried to reassure the public that they are safe.

Boeing invited members of the media, airlines, regulators and pilots to Washington state in a bid to assure them that the 737 Max is safe to fly. The aircraft were grounded after two deadly crashes.

Boeing is giving updates on the software fix to it's troubled 737 Max jets in a bid to get the plane back in the air.

Authorities in Ethiopia are preparing to release preliminary findings on the cause of the crash of an Ethiopian Airlines Boeing 737 Max 8 jet that killed all 157 people on board.

Old reports of safety concerns regarding Boeing's scrutinized 737 Max jets are resurfacing and training procedures are getting fresh scrutiny.

President Trump is nominating Stephen Dickson, a former Delta Airlines exec, to lead the Federal Aviation Administration while it is being sharply criticized for its oversight of plane manufacturers.

The news comes amid reports Boeing's safety analysis of a new flight control system on the 737 Max was flawed; and that Boeing is now under federal investigation.
