How could an SST like the Concorde get from cruising altitude down to

I believe with the two inboard engines on reverse thrust the outer two
on idle. On my only Concorde flight (a test with volunteer passengers)
we descended from cruise height with two engines on reverse thrust. All
I remember was that the clouds below seemed to come up very fast!
