We have the voice recorder data, and there’s no allah-praisin’ going on. Isn’t that relevant?
I am all for exploration for links to islam when stuff like this happens, but in the absence of any such links to date, and with plausible non-islam evidence emerging, it’s time to let go of the longing to hang this around Mohammed’s neck.
When you or I are alone, do we pray aloud, or just in our minds?
