Every commercial flight has trained, armed undercover personal on board....Awesome.
It's those small private jets and planes that need to be monitored with the ready to shot down (STA missile) responce across every part of this country.
Police agencies should be trained and have portable STA missile capability on the ready if needed.
Around Stadiums, Shopping Districts, Goverment Facilities, and around any multi-social populated areas.
No fly zones mandatory and with strict shot down policies.
Shot down ask questions later concept.
