Eagle Lander 3D is written by Ron Monsen.
I would like to extend my thanks to Frank O’Brien and Hennie Frik for their assistance in this effort.
Frank is a historian of Apollo and offered much material and consultation for ‘getting it right’. Frank is also one of the editors of the Apollo Flight Journal – a NASA based historical account of the Apollo landings. http://www.hq.nasa.gov/office/pao/History/ap15fj/
Hennie Frik did a tremendous job 3D modeling the complex LM ascent stage. His meticulously detailed main ascent stage and every nuance of the many antennas are worthy of the best professional 3D modelers.
