Kenny - I thinks it's understandable that someone from a multi-role, multi-ordnance fighter would scoff as you are. However, don't discount the impact of MDS culture, especially with a single mission, single load-out (more or less) fighter. An air-to-air fighter doesn't have the myriad of ordnance and potential takeoff variables that say, an F-16 has. On most take offs, the TOLD data is a square filler. Sea level bases and an overconfidence in a/c and engine capes could easily create an environment where things like density altitude is not in the cross-check. I'm not saying it's right, but I can understand how they got there.
For the the first two decades of the F-15's existence, pilots didn't even compute TOLD. Every takeoff you rotated at 120 knots. Full aft stick to get the nose moving and adjust after that. Mil, Burner, missiles, training load, clean, 1, 2, 3, bags... didn't matter. Or did it? I'm sure if someone took the time to compute rotation and takeoff speed, they would have varied somewhat in all the different scenarios. Takeoff speed? WTF is that anyway?😜 It started in FTU with the aborted takeoff discussion. The guidance for some "issue" on takeoff went, that if you're at or past 120 with the stick moving back to rotate, then you're going. If you're not there yet, then you abort. Of course, there was always the caveat that if it was a "no shitter" (whatever that is was up to you) you could abort above that knowing you had the hook. That was for mil power on an 8K runway. Anything longer just gave you room to work with, but didn't change the decision process. How's that for TOLD? Even after we started putting TOLD numbers on our line-up cards, not much changed.
I also wouldn't discount the effect the FTU training environment may be introducing to this cultural problem. If you actually read the report and look at the data, it's pretty clear that there's a huge trend throughout the F-22 community to rotate early, even in FTU. That makes it pretty clear this stuff is being taught early on. Another thing to consider - There's probably a bunch of ex-Eagle guys wearing coats and ties and teaching sims and academics who may be throwing out some questionable techniques and info from "back in their day" that's being gobbled up and retained by "Stanley" the newbie Raptor dude. I think back to more than a few bogus techniques I had to unlearn thanks to some retired F-4 guy, now sim instructor, throwing out something he thought worked great. Some bigger stuff but mostly little things. I ended up with an audio only version of my HUD tape during what anyone would argue was the highlight of my career thanks to one of those sim instructors teaching me how to set up my cockpit for start. But, I digress.
It's pretty clear from the report that this is much more than one guy not reading his line-up card and being a dumbass. That's not to say your points about not checking safely airborne, etc. aren't valid. As others have mentioned, we're not talking about a huge amount of time from brake release to gear up and I'm sure muscle memory and expected timing took priority over a more accurate check. At least the result was a shiny a/c underside, some personal shame and hopefully a better approach to takeoff ops and not another nickle in the grass.
