Considering Mahboob is no longer here - it opens up a number of different possibilities.
I suggest:
Now that we've learned the extent of the disaster the BLA represented - here's a possibility...
Mahboob may have started confidently thinking it would only take a bit of "fixing" to get this BLA filed. After examining the BLA he probably discovered the true extent of tragedy the BLA as constructed, represented. I remember Mahboob's positive announcements of progress, and impending completion dates, but they obviously didn't pan out.
He WAS well paid for the task he didn't complete and probably couldn't complete. Lucky Mahboob.
I hope Chris Recknor is more successful in shepherding the BLA to completion!
IMO
