Bob Ebeling, Challenger Engineer Who Forewarned of Shuttle Disaster, Dead At 89 (huffingtonpost.com)
An anonymous reader quotes a report from HuffingtonPost: For three decades, retired NASA engineer Bob Ebeling blamed himself for being unable to stop the 1986 launch of space shuttle Challenger. He had warned that the shuttle might explode, and it did shortly after liftoff, killing seven crew members. Ebeling was one of five engineers at a NASA contractor then called Morton Thiokol who warned the space agency that cold temperatures predicated at the time of the launch could prove disastrous. The warning was ignored. The night before the launch, Ebeling reportedly told his wife, Darlene, "It's going to blow up." He told another daughter, Kathy Ebeling, that he had toyed with the idea of bringing his hunting rifle to work to threaten NASA not to launch, according to an article last month in The Washington Post. In the final weeks of his life, however, thanks to an outpouring of support following a National Public Radio story in January on the 30th anniversary of the disaster, Ebeling, 89, finally found peace. Ebeling died Monday in his home in Brigham City, Utah, after a prolonged illness with prostate cancer, NPR reported.
There was a a "product" and a "sale".
The product was the first teacher in space. The sale was the State of the Union address by President Ronald Reagan. According to various reports, Reagan wanted to chat with her while she was in orbit on national television. NASA and the administration categorically denied that the launch was tied to the speech.
Note also that the exact same causes were also listed as contributing factors in the loss of the Columbia.

They were shipped long distance by train so that they could be manufactured in the district of someone important to funding.
That "someone" was Senator Jake Garn of Utah, who chaired the appropriation committee for NASA's funding. He not only had the SRBs made in Utah, but he also got himself a ride on the Space Shuttle at a cost of tens of million to the taxpayers, despite being completely unqualified and spending near all his time in space puking from motion sickness.
Make the SRBs on-site and avoid the need for O-rings entirely.
They did not have to be made on-site. They could have been made in a single piece anywhere on the east or gulf coast and moved to the launch site by barge using the Intercoastal Waterway. That was the original plan, before Senator Garn used his chairmanship to have construction shifted to Utah, increasing the cost, and decreasing the structural integrity.
Additionally, googling "Robert Lund" finds articles from 1986 naming the others: Joe Kilminster, Jerry Mason, and Larry Mulloy.
While those 4 all had a part, the one ultimately responsible appears to be Joe Kilminster, who recommended the launch, and should have listened to Ebeling.

"Calvin Wiggins, who was demoted to deputy."
"authority previously held by Jerry Mason, senior vice president of Wasatch Operations, and by Robert Lund, vice president of engineering."
"It was Wiggins, Mason and Lund--along with vice president Joe Kilminster--who overruled the safety warnings raised by rocket engineers the night before Challenger was launched."

Also says Jerry Mason, Joe Kilminster and Bob Lund, as well as Larry Mulloy
"When Larry Mulloy, MTI’s SRB manager, heard Roger’s explanation for the failure, he refused to accept it."
"nothing was acceptable to Mulloy who insisted Roger did not have enough data to support a no-launch recommendation."
"Larry Mulloy asked MTI’s vice-president and program manager Joe Kilminster for his launch recommendation, to which he replied, “Based upon the engineering information that was just presented, I do not recommend launching Challenger tomorrow.” With those words, relief flowed over Roger’s body in a wave of euphoria. Thiokol had done it. It had convinced them to stop the launch. But euphoria quickly turned to despair as Larry Mulloy asked MSFC’s Deputy Director of Science and Engineering, George Hardy for his recommendation."
"Roger and Arnie watched as MTI’s top executives, Jerry Mason, Joe Kilminster and Bob Lund continued to twist the engineering data to support a launch decision."
"The managers then handed their new launch criteria to Joe Kilminster and asked him to present them to NASA. After reconnecting with the attendees at MSFC and KSC, Kilminster issued the launch support rationale and recommended that the launching of Challenger proceed as planned."
