I would like to know if Vickers had even a slight head cold????Even without it---driving/flying---imagine this-- accelerating, turning head to look in mirror, track banking changes(tips) turning head back frontwards, turning car, looking in mirror, more track angle (tip) looking back to front, increasing turn, turning back, check mirror, track angle increse, turn rate change, check mirror, spin starts, close eyes, rotational rate increse, abrupt negative Gs and deceleration, impact, open eyes, impact, rotation, more deceleration, rotation, panic ,

these guys are all pretty good drivers but there are many physical things plus physics that effect high speed objects along with there human components
