Are we absolutely certain they did not see it? If pre-occupied with an 'overspeed', they would be cognizant of VSI, but, like Altitude, they didn't remark on it till it went "critical"? Overspeed recovery involves an "abrupt" mitigation of descent, unlike any STALL recovery? Also, the VSI was fluctuating, so why trust it implicitly? I think they were flying in a 'blend' of IMC and "seat of pants". Unfortunately, they were relying perhaps a little on the way they "Felt"? So, again, OS wants instant 'g', to the "limit" (and it is available, with protections?). No pressure to endure a ND of 30+ degrees and taptoes to wait for wings 'reload'?
