Tell the new boss, Willie Walsh, Skydancer, Just been appointed today. Did a good job on Aer Lingus until he got fed up with the government faffing around. Veeeerrry interesting to see what he does with BA. $20 to JFK anyone? And lots of job cuts.
If he buys A380's they'll have to do a good deal. But BA is a traditional Boeing airline.
Habu, you can get an engine to stricken aircraft in a couple of ways.
The 747 can actually carry a fifth engine inboard of the working engine on the left wing. That is quite common but as often as not the engine is ferried in the back of a cargo aircraft chartered for the purpose. Quite expensive in fact. For a 747 you can always three engine ferry while empty.
Of course there is always a semi trailer as creamo says, air ride suspension of course.
Edit wow that was quick I must type faster.
