From page 3 or 8:
If the turnaround began at IGARI N6.92E103.58 and ran through N7E103.7 and around to N7.2E103.7 as it turned north and then west, it would have taken about 25 miles and 3 minutes.
If the heading west then is measured from N7.2E103.7 at 17:22 to Penang Island N5.3E100.3, the distance is 268 miles, meaning that it would have reached 18:22 after 557 miles in 60 minutes and that is pretty fast especially with a turn at Penang.
The 530mph is thus very conservative and even at that speed makes one wonder about all the altitude changes that were supposed to have taken place.
The Flight of the MH370 [2] from page 3 [or 8] of the report:
16:41 — Kuala Lumpur Airport N2.73E101.71 — Takeoff.[0]
17:19 — Tansponder and ACARS dismantled. Start of turnaround at IGARI N6.92E103.58 northeast through N7E103.7 [325 miles]
17:22 — N7.2E103.7 — Turnaround complete after 3 minutes and 25 miles and now heading west. [+25 miles]
17:51 — Penang Island N5.3E100.3 [+268 miles] followed by a turn to the northwest.
18:22 — N6.6E96.3 — Heading northwest from Penang Island. Malaysian military loses radar contact with plane at this point. [+289 miles]
After travelling the last hour from the turnaround averaging 557mph [268+289] with a turn at Penang Island pilot cuts power to nonessential systems to evade radar, takes it off autopilot, and begins to fly manually slowing down in preparation for an upcoming turn. This probably cut air/oxygen to passenger compartment causing hypoxia for all but the pilot.
18:25 — Log On Request automatically sent to satellite to restore power just cut 3 minutes earlier but it takes 4 more minutes for the power to kick back on.
18:29 — N6.85E95.45 Turning Point Southwest. Plane flown manually for 7 minutes averaging 530mph for 61 miles and then the power kicks back in at this point after it turns South. [+61 miles]
—— — 968 total miles from takeoff to here
18:39 — Unanswered ground to air telephone call #1. Was it triggered by Log On Request??
19:41 — S2E93 — 634 miles @528mph Another smaller turn south required here.

23:14 — Unanswered ground to air telephone call #2. Was it triggered by a Log On Request that’s not listed???
24:11a — S36E90.5 — 745 miles @496mph [same direction but slower speed]. Total to this point 3955 miles.
24:11b — S30E97.5 — 527 miles @351mph [eastward and slower speed to center of the search area]. Total to this point 3737 miles.
24:11c — S27.5E100 — 583 miles @389mph [eastward and slower speed to northeast part of search area]. Total to this point 3793 miles.
