Wrong on both counts. It removed by personal demand of JFK over the recommendations of USSS, and it would have shielded him from the shot. Might not have been bullet-proof, but it would have made an effective shot a lot more difficult. In any event, that was the trigger to removing the Presidential option to discard USSS security precautions.
Nope. It's well documented. Jim Lehrer spoke to agent Forrest Sorels at Love Field about whether the top would stay on given that the weather had cleared. Sorels ordered the top removed since it was sunny. The top was actually in the trunk of the limo in case it started raining. When the decision was made, Kennedy wasn't even in Dallas yet. The top was a measure for protection from
weather. Whether or not it might have deflected a bullet enough to make a difference is
pure speculation but the fact remains, the bubble top was not a security measure.
Wrong again. Clearly you have no knowledge or understanding of air defense operations and the RoE in effect today. And the only reason UA 93 wasn't splashed is that it crashed before that could happen -- in fact, unarmed DC ANG F-16's up on a training mission were going to ram it before it got too close to DC (no armed aircraft were in a position to get there in time, and no SAM's were in position). That was documented in an AW&ST story shortly after the event.
Somehow you went from an unidentified GA aircraft in a presidential TFR today to an identified hostile on 9/11 after three planes had already been used as missiles, and you went from SAMs to interceptors.
Nevertheless, the pilots you're referring to were not airborne on a training mission. They scrambled in response to an alert from the Secret Service, but there was no time to arm their planes with missiles. Also, whether they would have rammed UAL 93 or not, they were not ordered to. They were simply told to protect DC. In fact, the 9/11 Commission determined that even though Cheney gave the order to shoot down non-responsive aircraft, that order was never passed down the chain of command:
“The NEADS commander told us he did not pass along the order because he was unaware of its ramifications. Both the mission commander and the senior weapons director indicated they did not pass the order to the fighters circling Washington and New York because they were unsure how the pilots would, or should, proceed with this guidance. In short, while leaders in Washington believed that the fighters above them had been instructed to “take out” hostile aircraft, the only orders actually conveyed to the pilots were to “ID type and tail.”
On a side note, I'm not aware of any corroboration of Sasseville and Penny's version of events that day, but their plan (which no one mentioned until 2011) was not the official "ROE."
