Looking at two men walking a few steps on the surface of the moon on french TV, i wonder how much it would cost to send an instrumented business jet equipped with an assortment of pitot probes on a few flights across the upper layers of the ITCZ?
I too wonder what the results might be to take away the glass and inact alarms in the ITCZ, revert to Alt Law and monitor crew actions. Sooner or later, this question as yet has not been asked, but it still has to be resolved.
