it's all systems go

You say it's all systems go to mean that people are very busy with a particular project. Work started on the indoor arena at the beginning of the year and it's now all systems go for a full programme of events over the winter. The Commonwealth has released its funds and it's all systems go. Note: This expression became popular as a result of its use during the launch of spacecraft in the United Sates in the 1960s and 1970s. It indicated that the spacecraft was functioning correctly and was ready for takeoff.
