Apollo 11 re-enactment – Pencils ready? Re-entry details

At Ground Elapsed Time (GET) 186:28 hours, Apollo Mission Control released the following details in relation to Columbia’s entry into the Earth’s atmosphere and landing in the Pacific Ocean (taken from the transcript at http://www.hq.nasa.gov/alsj/a11/a11transcript_pao.htm):

This is Apollo Control 186 hours 28 minutes Ground Elapsed Time.

8 hours 35 minutes to entry.

Crew of Columbia still asleep at this time. Some 2 and a half hours away from wakeup time at 189 hours Ground Elapsed Time.

Because of weather avoidance in the prime recovery zone in the mid-Pacific, southwest of Hawaii, it has been decided some time ago to shift the landing point – aiming point – some 215 nautical miles downrange from the pre-mission aiming point.

And all the numbers concerned with entry and post-entry events have been generated, and we shall forward them at this time.
