It amazes me how people feel a need to comment about an event like this when their comments betray how little they know. Just an observation.
Anybody know what AOB on a classic/747 will give you a pod strike at high ROD at touchdown?

Pod strike around 8.7 degrees at 256t and 7.2 degrees at 285t- at min body pitch angle. Shows you how little I know. (or do I have to go into the graphs further?)

Hi Folks,
Just to prove the earlier posts that 747s CAN land on rwy 06 at Perth, here's a recent photo (Nov 2007) of a South African Airways 747-400 landing on runway 06:

Hi Virgindriver,
From someone who lives almost directly under the final approach for RWY 06, I can most definately confirm that 74's often land on 06 in a strong easterly wind. There was also an A340 last week landing on 06.

virgindriver and DirectAnywhere..........
Roll angle for a podstrike is as you say, dependent on the variables quoted, but podstrike can also occur at a less than anticipated podstrike roll angle vs. weight if the landing is..........ummm........'firm', and there's wing 'flex' as a consequence. It's happened before, and it'll happen again.
In fact, wingtip strikes are even known to have happened when at the same time the associated wingpod engine(s) has escaped 'unstruck' so to speak! Seem to recall an Asian carrier had it happen on a 737 a few years back. Crew were unaware that a tipstrike had occurred on landing until a somewhat less-than-impressed passenger told the CAs as he was disembarking that he'd seen bits coming off the wing tip as the aircraft touched down.

That's what caused those!! I'd been wondering who had been doing broadies on the runway edge like that. Would have to have been rather off centre to be over that far. Those easterlies are known to be intensely gusty and variable too at times...

3 engined B747-300 PH-ML
I'm told a B747-300 PH-ML last night didn't get too far into the flight before suffering a rather impressive engine failure, followed by a return to PH. Many unhappy SLF standing 10 deep at the Q club bar, drinking their way through the long delay whilst an engine change carried out. Same airframe eventually departed some 3 hours later.
"Souvineers" from the failure found by punters on the ground and handed in the WA police!

Louis, I'm not sure where you get your information from, but I can assure you that the "same airframe" would not have departed only three hours late after an "engine change" in YPPH. There are no spare engines sitting around Perth waiting for a "a rather impressive engine failure" to occur.

Woftam, the failure, complete with bits falling off most certainly did occur. verified. The report about the engine change came from a normally very reliable source, but i can't verify 100%. Doing the math on the ata ML, it was probably closer to a 5 hour delay.
But then, how many spare classics do they have sitting around at PH??
