KH-4B. The launch vehicle had a very cold boattail due to a hose discovered to be leaking away warming air to the boattail. The boattail was colder than usual, below freezing. Based on earlier tests of the Thor for just that condition, as relayed by Ed Dierdorf, Thor chief engineer at the time, the temp low was of no concern.
The only problem was that those tests were made with a Thor that carried a Rocketdyne engine lubricated with "lube oil". The Thor being launched used a fuel additive, "Orinite" (like STP "super snot"). The technician that pumped the Orinite into its cannister later stated, "It wasn't for lack of orinite. I put it in just like the procedure said, and I could feel when it was full (with the hand pump). To make sure, I gave it another slug."
That "other slug" cracked the output valve that was only supposed to be cracked by turbopump output pressure. When it cracked the output valve a bit of the "honey" squirted down the tube toward engine bearing jets. This line had a low spot in it by design. The Orinite settled there. When it was chilled by the low temp air at lox loading, the Orinite formed a plug.
Unaware of this chain of circumstances, Launch Director Philip Payne made the decision to launch. The rocket (carrying Agena D and payload) flew for 18 seconds, then wiped out its gears, causing the turbine to overspeed and shed its vanes. These punctured various parts in the boattail like machine gun bullets. With loss of power, the rocket fell not far from the launch pad into Bear Creek canyon.
The final cause was therefore found to be loss of engine lubrication at startup.

Unusable orbit; would have been NOAA 7. At engine start up, one of the booster engines suffered an internal fuel leak, causing it to run at about 80% thrust. As a result the booster was low on velocity and heavy on propellant over much of its flight and ran an incredible 50 seconds longer than the nominal burn. The NOAA Advanced TIROS payload was designed with no direct communication with the booster, and unaware of the booster problem, at 375 sec after liftoff attempted to separate with the booster still firing. The booster's continued thrusting defeated the payload's attempt to perform the required pitch maneuver. When the payload fired its apogee kick motor, it blew the top of the booster's liquid oxygen tank off. The spacecraft survived all this, but the resultant orbit was highly elliptical rather than the desired circular sun-synchronous. The mission was a total loss.

Ocean surveillance; aka White Cloud type spacecraft; Navy Ocean Surveillance Satellite; PARCAE. Other sources give the payload designation ABSAD. The failure was caused by a loss of lubricating oil to one of the booster engines, causing the engine to fail approx 200 milliseconds before it was to have shut down on guidance command. The asymmetric thrust pivoted the booster around approximately 180 degrees, where it stabilized in a retrofire attitude with the sustainer engine still firing. It descended back toward earth through its own exhaust flame and exploded a couple of minutes later.
