What does the scan show?
A person reads every report. Corrections are made by hand, to the data — titles, dates, names, which pages belong together — never to the scans, and they can take a while to appear.

NWA Chief Per[sonnel] [guess: Engineer] had been [guess: alerted] to field to keep [guess: collaborate] range, etc. [guess: Entire] Company had been contacted [guess: for] advisement in [guess: every] [guess: problem], [guess: flight] characteristics with airstairs extended, whether opening (stairs [guess: extended] about 20° in flight, possibly more with man's weight on them) would be large enough for a man to exit. Being assured us there would be no controllability problems, that they would get experts work- ing on range problem also, that they had dropped 2-300# [guess: leaves] out [guess: air-stair] opening in flight and that man could probably get out.

NWA Communications people also had arrived at field to assist in in required [guess:pur] new [guess: pot] in [guess: and] [guess: other] communication problems.
Mr. Nyrop [redacted block] four supervisory pilots, b6 1 performance engineer, many others on the scene (MSPFO) for b7C assistance.

2345* Flight at 7000's, 160KIAS, fuel flow (FF) 4500#/engine, flaps 30° gear DOWN. MSPFO advised they would have even more severely limited range in the flaps 40° position. Crew given preliminary information on opening range TAS (170K), weather, air- ports available but not [guess: any] Sta and RNO, minimum obstruction clearance altitudes, etc.

2155 MSPFO asked for stewardess best recollection of exact content of HJ briefcase. She got on radio and gave following basic information:
- Eight red sticks, about 6" x 1" in left corner of [guess: brief] case, "look like big firecrackers." Two rows of sticks, four on top of four. - Wire attached to dynamite with red insulation. - Battery "like flashlight battery, but about 6" high and as big around as my [guess: arm]." - Red sticks are about the color "of my uniform".

0205* Crew called HJ and asked him if everything was O.K, and he replied that it was. This was apparently the last communi- cation the crew had with the HJ.
---
2210* Crew reported oscillation of cabin rate of climb indicator. This probably due to HJ weight now on stairs, stairs extending further, resultant effect on cabin pressure. May be best estimate of when he exited airplane.
---
MSPFO advised crew that range to RNO now looked good (air- plane now at 10,000, 170K [guess: near] RNO, flaps 15°, FF 4000#/ hour/engine, [guess: TGT] -7°C. MSPFO calculated TAS and range from this data.
