The Federal Aviation Administration is considering temporary flight reductions in and out of Newark Liberty International Airport, and it's launching a safety task force.

The Philadelphia Terminal Radar Approach Control suffered a new problem that briefly led the FAA to issue a ground stop while it ensured redundancies were working as designed. The FAA said operations have returned to normal.

The Newark airport had hundreds of flights delayed following a telecommunications issue on Sunday, just two days after a brief outage happened on Friday.
