Real Time Data production is on board already. Boxes that can survive almost any impact and record crash data up to the last tinkle and clunk are onboard already.
This leaves the deployable. Ejected at what stage? Doesn't it become just a crashing projectile with parameters of its own? Unrelated to the A/C impact??
Quite the salesman, this Hall fella. If Rolls can sell 24 hour chock to block engine "Care", then........ Gild the Lily? ACARS had it down to the nth, but fell short, because its mission is Maintenance Productivity. Change the mission, change the gestalt.
