I got the chance to watch it this morning. Learned a lot. They had interviews with several vets and this included many members of the 50th Combat Engineers.
Betcha not too many folks know about the fight in the Aleutians. If you are among them, please take the time to broaden your horizons about the guys that fought there.
It was here that the Americans found the first intact Zero that had crashed in the Aleutians. How did that happen? Well several men were flying together and one of the guys was getting really sick. He chose to let it go outside the aircraft and as he did he called to his fellow flyers. Told them he spotted a crashed plane below. From this the Allies were able to study the plane and learn much about the construction. Thank God for air sickness! 
Two other pertinent points that pertained to the 50th Engineers:
Number one: It was here that the first experimental airfield was created in 1942. Because of the inhospitable conditions, the engineers had to get creative. They placed metal mesh that connected together and formed the runway. It was a success and used many times after during the war. You can see a photo of it here:

Another obstacle was overcome again due to engineering igenuity. Because of the terrible terrain (mushy, volcanice, etc.), the troops were having a very difficult time making headway up the hills. It would take hours and hours just to move an artillery gun, etc. 500 feet. Most of the equipment would simply sink. Well a few of the engineers got a big rig up to the top of one hill, then set up what worked like a ski-lift; cables that ran up and down and assisted the men and machines. Go engineers. Love you guys!!
