That’s what I liked about the test rig. It was one thing to handle the individual parts, but seeing it all put together and running was truly impressive.

My Dad was a USAF Specialist on the 3350, the motor of the B-29 (and other craft.) But whoever wrote that is incorrect. If there were oil in any of those lower cylinders before firing it would bend the rods. The props were turned by hand before the motor was ever attempted to be started. If there were oil in a lower cylinder the prop would stop rotating. At that time the Crew Chief, which is what my Dad was, would remove the lower spark plugs and drain the cylinders. I didn't watch the video, but I can tell you they were not clearing any oil.In the video when the engines turn a few rotations and stop, that is clearing any oil from the lower cylinders.

Dunno what became of this bird:
The US military could soon be flying one of the fastest helicopters ever
Helicopters have been very versatile, serving as anything from transports to gunships. But they haven’t been all that fast. According to AirForce-Technology.com, the fastest helicopter in military service is the CH-47F Chinook, which has a top speed of 195 mph.
That could change if the Sikorsky S-97 enters service with the U.S. Army. With a top speed of at least 253 mph, it blows the competition away — even if it isn’t quite as fast as Airwolf.
But hey, the technology is getting pretty close.
But the S-97 isn’t just fast. According to Lockheed, this futuristic helo, with contra-rotating main rotors and a pusher in the tail, can carry AGM-114 Hellfire missiles, Hydra 2.75-inch rockets, and will shoot a 7.62mm machine gun or a .50-caliber machine gun.
Four can fit inside a C-17 Globemaster transport. Lockheed notes that the S-97 can also carry up to six troops in its cabin.
Lockheed says that the S-97 could fill other roles besides the armed reconnaissance role that the AH-64 Apache has taken over, including as a search and rescue helicopter, a multi-mission special operations helicopter — and there’s even a proposed unmanned variant. The S-97 can also be refueled in flight.
One area the helicopter could excels is in the so-called “high and hot” climates that have often limited other helicopters. Lockheed claims the helicopter can hover at 10,000 feet in an air temperature of 95 degrees
Thought I would add my $0.02.
After spending over 15 years of my career working on the weapons systems of the F-14, I think it deserves mention. I got to work with some of the engineers, pilots and technicians that made this aircraft perform. When it worked properly, it was flippin’ awesome.
Lots of stories that I have and I have an outline of a book that I plan to write about my experiences...
