Here are some photos of my spotting from the Smithsonian Parking Lot & the observations tower. These are pictures of planes landing at runway 1R.
A couple United CRJ-200s.
A United 737.
A Porter Bombardier Dash 8-Q400
A private Challenger
Now here is my pictures inside the Smithsonian (I know it’s not really spotting, but it’s planes)
Couple shots of a Air France Concorde.
Finally the SR-71 Blackbird itself.
Hope you enjoy! Sorry for quality, taken on my phone. Also, if I thought it was the wrong plane, respond and I’ll change it!
