On the ground or in the air?
If the alleged "first" explosion was on the ground, then it could have the plane engine dropping. Reportedly a plane engine detached and smacked into to the ground.
When engines croak and catch fire, do they "explode"?
However, being in NY, it is a little bit on the suspicious side.
There goes the "Airline recovery", regardless. Anybody who was nervious about flying is not gonna step on one of those without dragging and kicking. That probably reduces family flights, since one skittish person will probably result in none going.
