air displacement of a 380 airbus nose cone causes air flow within immediate port and starboard engines to be un-matched with fuel ratio; ie too much air pressure in ratio to fuel thus causing weak combustion mix; leading to temporary engine stall; note when air pressure reduces engine re-ignites and causes combustion explosion that the engine cannot withstand! this is especially the case when plane is flying in advancing cross headwind when aircraft ascending! remedy is to have auto-matic engine fuel mixture compensation control; ie air intake sensors on immediate port and starboard engines so that on board computer can enrich engine fuel and decrease fuel ratio when air intake drops to normal levels.

Better safer Jet Engines if new magnetic bearing were to be used!

Magnetic bearings support the highest speeds of any kind of bearing; they have no known maximum relative speed and permanent magnets be can be bult up in sections and be then be just as light weight as a normal bearing;
This is acheived by seriously chilling neodymium magnets and then applying magnetic energy as usual. This results in massive magnetic power far greater than any previusly known permanent magnet, fact!
