I know that this is my first post here and unfortunately it has to be on a subject caused by such a sad event, but I read earlier today on another aviation forum a post by someone (I presume a ramp worker or fellow pilot), who claims they saw the aircraft in question a few hours earlier in Newark doing ground runs on one of the engines, with one of the pilots outside looking at it, while the run was performed, thus delaying the boarding and subsequent departure.
Perhaps there was something that happened earlier yesterday, which contributed to this accident.
Anyhow, RIP to the victims and my thoughts go out to all those affected by this
