70 aircraft landed on 16L+R yesterday. About 45% of those came via CALGA.
So 40 aircraft over a 10 hour block 5nm away can't fit in with a heli transiting for 3 minutes and using 2500 feet of vertical C space for the drop from 10k?
I fly all the time in as a pax up and down the j curve as well as private (well, not enough of that one), I have yet to get close enough to Somersby on return from Brisvegas...
