Here is a Youtube video with a cogent analysis of publicly available information about the tragic airplane accident at National Airport this past Wednesday. The video is about fourteen minutes in length and I think for any reader it would be time well spent.
I was in Washington earlier this week to argue an ex parte patent appeal before the PTAB. The way I arrived in Washington on Tuesday was through National Airport. Yes, the same approach from the south, with a glide slope down to Runway 1. My flight was not asked to swing over to Runway 33.
My return flight from Washington was on Thursday, through Dulles.
