Salute!
Yeah, Buster, many of we colonists liked the Pratt motors as they were "robust". OTOH, the GE and Rolls motors were very high performance and lighter ( more thrust per pound). So I had a thousand hours in the Allison /Rolls fan in the A-7D with no problems, Great fuel consumption and so forth.
Best example of the fan bypass in the TF-41/Spey motor was ingestion of a flock of seagulls at Myrtle Beach. Motor coughed, belched and lost power. Pilot turned back and landed opposite rwy to show us the roasted birds!! Some were impaled on the bomb racks, but a few were lodged in the bypass duct. Suckers were toasty!
Gums recalls....
