Had a look at the engines a couple of days ago. 1 & 2 have scrape marks along the cowlings, but 4 suffered the most. One engine has to be replaced and the others are having the cowlings replaced...will take a couple of weeks to get the parts delivered and fitted...getting the replacement engine will be the hold up!!
Spoke to a 747 F/O about it and he wouldn't believe that 3 engines struck the runway!! he just said "How is this possible?"
