It does make sense, the pilots wanted to get Tina off the plane, take off with stairs partially open would achieve that.
The 302's are agent summaries which are less reliable than the pilot transcripts.
Read that pilot transcript.. carefully,, it is the most accurate for order of events
Just because you say something doesn't make it true.
Consider the path of a transcript:
1) Cooper makes demand to Tina.
2) Tina relays demand to Florence via airphone.
3) Florence writes down and relays demand to pilots.
4) Pilots relay demand via radio to 3rd party who provides the patch through to the FBI.
5) 3rd party transcribes the radio communication and passes it on.
Now this process is remarkably more accurate than:
1) Tina, Florence and pilots convey info to FBI during interview.
I'm not buying it. Furthermore, I addressed the phrase about the airstairs being down inflight above. You're taking one piece of a transcript and declaring
it accurate but other things that contradict
it inaccurate. What do you base this pronouncement upon? How do you know that Cooper didn't use the word 'lowered" (actually "lwrd" in the transcript) as an adjective as opposed to a verb? How do you know that the pilots interpreted the initial Cooper demand via Tina and Florence properly as a verb or an adjective?
This is why I say that these things have to be read carefully, not just literally, and certainly not selectively.
