Hi,

Thanks for info.

a. What happens to the piece of the breakable link that is part of the
bar
that stays with the plane ?
Does it go flying with the plane to be removed later, or... ?

Yes, and it is later removed by the Plane Captain as part of the "Turn
Around Inspection" after landing.



b. Any info on the newer, I think, types of hold-back mechanism that do
not
utilize the breakable bar, but apparently use some type of captivated
spring/cam mechanism as part of the bar (permanently) ?

Not part of the Steam Catapult system. The holdback may change with the next
generation of launch systems.
