Air Force, Navy Ground Hundreds of Planes Due to Faulty Ejection Seat Parts

All your equipment was built by the lowest bidder. Or someone's palm got greased and it was made with the cheapest parts to increase the profit margin.
What's really interesting is that Martin-Baker is probably still being paid.

I recall going through all sorts of similar groundings. At least the system still works.

I'd sure hate to be piloting one with an inop ejection seat.
