They both have been extremely lucky seeing the damage on the 404. Incidentally was the 737 not TCAS equipped (or the 404 not squawking at the time ?) someone knows if Namibia has not yet signed the ICAO ACAS recommendations ( not yet globally mandatory, I agree )
To the Namibian defence, the earlier collision mentionned in the article (C141/Tu154) did not involve Namibia directly.
