QF Flight returns to SFO after engine blows up

Longer trip than normal for QF73 today

Now if they could just figure out how to supply fuel and controls to the 5th engine, they could make it shorter trip Then the extra 20% thrust would more than compensate for the extra drag ... but the extra fuel burn may result in "landing" somewhat sort of the planned destination

Although not common incidents, give more sway to those 4 engined QF planes than the 2 engined V-Aus ones.

The hole would indicate something (ie turbine blade) was uncontained.
And yes both ATSB and the NTSB will investigate, QF73 this afternoon will operate with 5 engines attached http://eu.airliners.net/aviation-pho.../4/0289429.jpg!

Ah yes, too many engines is never enough......

'4 Engines 4 Long Haul'?

So is a 4-engined aircraft twice as likely to experience an engine failure than a twin-engined aircraft, thus making the 2-engined aircraft less likely to require a diversion/return and hence more likely to arrive on time?

Ah, better to be late than dead.

Like when I see people running across George St in Sydney traffic against the don't walk to save 15 seconds and have a higher risk of death and maiming. Personally I prefer to reduce my risk and be 15 seconds late.

Everyone has a different measurement of what's important.

Unlike Piston engines, Jet engines have a higher probability of failure for aircraft with 4 than 2.

Keep in mind no aircraft has suffered two independent engine failures that would not have failed 4 had the aircraft been a 4 banger, in which case having two or 4 would have made no difference, other than affecting the gliding rate of descent.

VH-OJQ is on its way to rescue its predecessor at SFO after arriving from JNB, here is a picture of it as a 5 banger landing in Sydney in case you have never seen one, you tend to look twice before noticing the extra bits!

You do look twice! I hope they paid the excess baggage charge for that!
