As for bad planning, the original plan was to stage the op six months earlier when the conditions were favorable.
You are completely failing to realize that the entirety of Operation Eagle Claw was based on terrible planning that the modern SOF community would never have accepted. You keep pretending that it was just the conditions that caused the failure; it was not.
Eagle Claw was a failure because it was a terrible plan. Even if the sand storm had not occurred, the entire plan was almost certainly doomed to failure. You don't know what you're talking about, which is why you keep insisting that it was only an issue of the sand storm.
To cap off a few of the problems with Eagle Claw:
1. There was a complete lack of human intelligence on the actual target area.
2. The operational plan basically admitted that the rescue team would have to wing it once they got to Tehran, because the intel was so incomplete. At the most important phase of the operation, they quite literally be making it up as they go.
3. The various different forces involved in actually carrying out the operation had never rehearsed together.
4. The actual members of the operation were not sure who was actually in charge of the operation owing to the lack of coordination. At the site Desert One this caused confusion because there wasn't anyone designated to take command of the site after landing.
5. Two the of helos had to turn back entirely based on the technical failures of their crews due to lack of training. Bluebeard 6 mistakenly assumed that a Blade Inspection Method warning light meant they were in imminent threat of crashing, because they had been trained in Marine H-53s, but the Navy's RH-53s had never had a blade failure after a BIM warning. In fact the RH-35's BIM indicator was just a caution, but Marine pilots were trained to believe it was a sign of immediate failure.
Bluebeard 5 also had to abandon the mission because the crew had accidentally blocked off a cooling unit when they were loading equipment, causing the aircraft to turn back. to make matters worse, Bluebeard 5 was carrying all the spare parts for the mission.
Honestly dude, what part of this gives you this idea that Eagle Claw was a good plan?
