I'd like to watch Glueball 'dabbling in 2 eng driftdown' AFTER he's lost 2 engines. I suspect that it's a bit late by then. Of course we should keep ourselves reasonably familiar with critical items in critical places. The MRA's won't move but you can improve your own situation by following the escape routes and (if necessary) dumping some gas to increase your level-off performance. Worthy of note that 'drifting down' can take a long time which can prove helpful when trying to clear very high terrain.
Come on Mr Glueball - get the books out - the great Aviation Gods are justing waiting for people like you.
