"* massive fuel leak in the left mid fuel tank (the beast has 11 tanks, including in the horizontal stabiliser on the tail)"any picture to proof this ?

"* massive fuel leak in the left inner fuel tank" think yes,but could be Feeder 2 instead.



"* a hole on the flap canoe/fairing that you could fit your upper body through" any picture ?

"* the aft gallery in the fuel system failed, preventing many fuel transfer
functions" there is a second gallery and lot of manual pump/valve switching available.

"* fuel jettison had problems due to the previous problem above" Heard they were dumping fuel for 90 min.

"* bloody great hole in the upper wing surface" Yes,indeed.

"* partial failure of leading edge slats" No,they are all driven by the same device and cannot fail partial.

"* partial failure of speed brakes/ground spoilers" Yes due to missing hydraulic.Another issue seems the function of Spoiler 5 and 6 -they are driven by EBHAs and should have worked both.

"* shrapnel damage to the flaps" Picture available ?

"* TOTAL loss of all hydraulic fluid in the Green System (beast has 2 x
5,000 PSI systems, Green and Yellow) "Correct .

"* manual extension of landing gear" Correct.

"* loss of 1 generator and associated systems" Associated systems are
supplied by 3 remaining gennys and below FL250 you can start the APU.

"* loss of brake anti-skid system" Why ?

"* unable to shutdown adjacent #1 engine using normal method after landing

due to major damage to systems

* unable to shutdown adjacent #1 engine using using the fire switch!!!!!!!!

Therefore, no fire protection was available for that engine after the
explosion in #2" This is a strange one,no doubt !

"* ECAM warnings about major fuel imbalance because of fuel leaks on left side, that were UNABLE to be fixed with cross-feeding" New to me...

"* fuel trapped in Trim Tank (in the tail). Therefore, possible major CofG
out-of-balance condition for landing" The fuel from the Trim Tank is normaly used after 12h of Flighttime.

To complete the list:-possible highspeed and/overweight landing-
3 burst tyres as a result.
-No reverser on No2 therefor still power (think much more than Idle)
from No1.

The crew did a perfect job,the aircraft design kept everybody alive-
but may be the A380 used all it`s luck for the next years.
