It USED TO BE, that if any approaching aircraft was larger than your thumbnail, it was too stinking close.
Nowadays, with all the stories that we, the public, are ‘allowed’ to know about, I have no idea.
I just hope that you did NOT need a laundry change, once you landed!
Thankfully, no...but I did say aloud: “Holy Crap!” involuntarily.
That just seemed too damned close to me! And I am not a shrinking violet, and I DO understand aviation to a degree. Someone else who might know less than me might not have even thought it was unusual, but I guess I know enough to alarm me, though perhaps not enough to be alarmed.
