Weekly history tournament - richest people - closing Oct. 3

[UpperKEES]

My solutions:

January 28, 1940:



The SAM and OC would actually fly during the charging of the final totem.

October 28, 1955:



More collectors were added to the bottom and the right. OC flies while charging the final totem.
   
August 30, 1930:



The blaster clears just enough space to build the last collector. OC charges the final totem after landing in the creeper.

April 19, 1957:



More collectors were added to the bottom and left. I forgot to display a drone that cleared the top right.

June 15, 1950:



Mainland was covered by collectors. OC first flies down and then to the left to charge the final totem in the air.
