Whilst that film is impressive I think Peter is talking about a "pad fall back".
Atlas-Centaur 5 pad fallback 1965 - Sonicbomb.com
Escaping one of those demands a fast decision (?automated) to intitate the abort and then a propulsion/guidance system that can get the spacecraft and occupants away from the fireball far enough fast enough.
50 years down the road from that Atlas-Centaur video it's still the case that any spaceflight, even a sub-orbital hop, using any current technology is sadly always going to be several orders of magnitude more risky than jumping on a commercial flight or using one's executive jet. I suspect everybody here knows that.......
Apologies for any thread drift.
