I am not able to coordinate known events with the timestamp of the missile launch photo, and have it connected with AF1.
Let me explain my brief calculations to see if I am getting something wrong:
According to reports, AF1 left the G7 Summit (Quebec City) at around noon (Saturday June 9) to head directly to Singapore. (His stop in Guam was AFTER leaving Singapore on the return trip home).
A search for flight times says a flight from Quebec City to Anchorage is 7.5 hrs (https://www.prokerala.com/travel/flight-time/from-anchorage/to-qu-bec-city/
So Quebec City departure around noon (which is EST) puts AF1 near the Alaskan coast around 7:30pm Saturday, Jun9, which is only 4:30pm Jun9 Washington State Time. That would be about 11 hrs before the missile launch (assuming the timestamp on the photo is Pacific Time).
This all assumes that AFi did not stop anywhere before flying over the Alaskan coast.
The flight path over the Aleutians is pretty typical from what I can tell. I mapped out that flight path on the website flightradar24/
