neil armstrong during that powered descent to the lunar surface. at the time the burn was initiated armstrong s heart rate was 110. at touchdown on the lunar surface, he had a heart rate of 156. and the heart rate is now in the 90s. we do not have biomedical data on buzz aldrin. the hatch is coming open. hatch reported coming open at 109 hours eight minutes five seconds. okay, houston, i m on the porch. roger, neil. okay, everything s nice in here. okay. can you pull the door open a little more? okay. okay. houston, this is neil. radio check. neil, this is houston, loud and clear. break, break. buzz, this is houston. radio check and verify tv circuit breaker in. roger. tv circuit breaker s in. roger.

entry at 75 statute miles. beginning blackout at 62 statute miles. main chute deployment, 10,500 feet. 11, houston, weather still holding real fine in the recovery area. looks like it s about 1500 scattered, high scattered and still three to six-foot waves. sounds good. roger. the earth is really getting bigger up here. apollo 11 lined up right down the middle of the entry corridor. we re a minute and 45 seconds from entry. blackout will begin 18 seconds after entry.
