Regulators probe engine blow-outs as older Boeing 777s suspended

The Saturday incidents involving a United Airlines 777 in Denver and a Longtail Aviation 747 cargo plane in the Netherlands have put engine maker Pratt & Whitney in the spotlight - although there is as yet no indication that their causes are related.
