As part of a statement that "Coop" must not have been very familiar with the ventral airstair, someone occasionally mentions Cooper having trouble dropping the stairs. The difficulty he had was hardly related to his prior knowledge of the airstair. The simple instructions that any idiot...

What does it take to demonstrate that the "FBI" flightpath chart is valid? That it truly shows, within the limits of its accuracy, the locations over which flight 305 passed after leaving SEATAC during the "Cooper" hijacking? First, don't get sidetracked into looking at the flightpath plot...

It has been said by someone that a person on flight 305 would have had to see past an overcast ("OVC") layer of clouds plus some lower cloud layers in order to see something such as lights at ground level. This reveals a fundamental misunderstanding of how cloud layers are measured and what the...

I made this up from data in the aviation weather report for 8pm, plus a tiny bit from WeatherUnderground.com history. Note that there is an isobar for each whole millibar number. It has considerable detail on surface wind in the western third of the state.

re. the difference between wind direction at SEATAC per the weather service and the direction (180, magnetic) someone identified as "ground control" stated to 305 just before takeoff: According to weather service (METAR) data at WeatherUnderground (historical) the 7pm wind at SEATAC was from...

Because the flight was unpressurized, the flight could have climbed at a rate no greater than 2000'/minute. Any higher climb rate would have been potentially uncomfortable or even dangerous for the occupants. This is why full-scale reading on the CLIMB rate meter at the FE console is 2000...

Just like Portland way out in the distance:) You did click the pic, right?:) You lookin at it on a smartfone? Don't to try to analyze any fine detail on it.

Actually, not odd. Because the comm logging doesn't include seconds, the last part of what was logged at 7:42 could have happened up to 7:42:59.

If I understand correctly, the pix were from when you were dropping the gear at too high a speed. If so, ALL is right with the simulated world. First, you were going faster than is allowed for dropping the gear. I'm glad you were able to avoid crashing:) Second, you get correct direction of...

I figured out that it would be easier to see the light pattern if I made the rest of it black.

The 12 minute burn is barely in the ballpark of what the flight reported. 5750lbs/hr/engine where they reported 4500. But the last three minutes seemed to have burned an inordinate amount. Just that last 3 minutes would be 9960 lb/hr/engine. More than 2x what they reported. Seems odd the...

Someone else might like to see a different scenario, but I would like to see an attempt to fly the path shown in the FBI flightpath map and matching everything possible to records of what the conditions were at the time (comm transcript, NWA incident report, av weather reports, NWS weather info...

Please don't say you won't fly unless everyone agrees:). Does your plane have a PAUSE button?

By rotating and cropping the FBI flightpath map, squeezing it down vertically, and adding perspective, this is sort of like the cities would have looked when approaching from the north on a clear night. Oh, yeah. The gold color represents the city lights.

Mr...45, A few days ago I asked about light patterns and you posted a pic of overflying Seattle in 1935 (I think). It really didn't answer the question for me. What I'm wondering about is if Vancouver and Portland look like they would have then (if you have that date set in, and assuming...

Tom, Did your analysis relate to the Mt. Hebo radar site?

It's still mighty purty.

I was describing what is on the FBI map, which I think is what Mr...45 was referring to. The NWA search map is basically the same positions but only for around the 2011 time frame, plus the addition of an interpolated position "A". Based on research re. the system that produced the data, and...

They went to 30° flap to slow down so "the guy in back" could get the stair down. This is also the doc that gives the "wheels off" time.

I see your problem. You're flying the wrong plane. It's supposed to be N467US, not N463US:)
