You can never have lower air pressure inside an aircraft than outside atmospheric. No implosion is possible. The most rapid decompression conceivable would only equalize pressures.
As I said, the scenario is highly unlikely. However, explosions do create a relative low pressure which will create a reactive implosion. It is like pushing a child on a swing. The push from up top causes the child to move towards equilibrium,
and then past equilibrium, causing the child to move back towards equilibrium.
Explosions typically create (or result from) a high pressure that causes matter to fly towards the lesser pressure. Should this process go to far (as in a child on a swing going past equilibrium), a reversal of the process will be caused, i.e. the movement of matter away from the explosion could cause a low pressure, resulting in some of the matter moving back towards the explosion.
Likely the resultant implosion will be tiny compared to the explosive decompression, especially if the rupture is not massive and the movement of matter takes a good deal of time, but it is entirely possible.
The point I was making was that such a resultant implosion would be occurring in the space once occupied by a now obliterated aircraft. That implosion will be inconsequential.
