I believe the FCTM is referring to a main gear failure,IMHO.
A Nose wheel exploding is going to throw debris all over the place........and highly probably down both engines.
As 4 Golds says Big BANG, Big YAW.
I know what I would probably have done, lets see what the investigation finds out.
If there is any signs of ingestion in either engine then it was not just a good call it would be a great call to stop rather than take possibly 2 dodgy engs airbourne.
