from milestone proposal
To History Committee members from Haruko Kawahigashi (Proposer)
I added (6) The social impacts of the MU radar to (B-1) Historical significance of the proposal with additional references [A1, A2, A3, A4] from Japanese newspapers, to show the MU radar's benefits to the people's lives. I also added reference number citation (e.g. [1, 3, ...]) to the proposal description.
