Sad and ultimately rather bitter:
Schweizer et al v. Sikorsky Aircraft Corporation
Of course, Sikorsky's interest in the S-333 platform waned once the U.S. Navy decided to switch the Fire Scout program to the larger
MQ-8C, based on the Bell 407 Fire-X platform. The S-434 program also failed to achieve any sales beyond the Saudi government, and even that customer "
returned several of the four-bladed turboshaft helicopters because they were wearing out before the end of their estimated service lives."
