Apollo 11's 45th Anniversary Crossword Puzzle
July 20, 2014

 

We came in peace for all mankind (wikipedia/nasa image)- RF CafeApollo 11 mission patch (NASA image) - RF Cafe"Houston… tranquility base here. The Eagle has landed." Where were you 45 years ago when you heard on radio watched on a B&W TV like I did as Apollo 11's 'Eagle' lunar module touched down on the moon - with less than 30 seconds of fuel remaining? A short while later Neil Armstrong and Buzz Aldrin became humans #1 and #2, respectively, to step onto the lunar surface. "We came in peace for all mankind," was plaque attached to the part of the lunar lander that stayed behind. Poor Michael Collins had to be content with orbiting the moon while is shipmates went to the surface. I created this special crossword puzzle this morning to commemorate the Apollo 11 mission and all the dedicated people who made it happen. BTW, have you seen my Estes Saturn V model?
