I genuinely can’t tell if I’m fckn dense or if these posts don’t make much sense…
It’s not you, no one seems to be able to make sense of the gibberish that pdw posts, I assume it makes sense to he/her/they/them.
The one thing you need to consider is that this poster has zero relevant experience to the events he posts about, he has a fixation with wind and quite possible experienced an incident caused by wind that perhaps caused a TBI, then you begin to understand!

In researching it became clearer that this aircraft’s flightpath transitioned from V-1/V-2 in a runway headwind to more-like tailwind by 200agl into/closer-up-to drier/hotter inversion (narrow transition / coolest at the surface).
Looking at the smoke plume, the upper wind appears to continue to follow the same direction as it was on the ground, at least to the approximate height the aircraft was able to climb to.

PDW's OK. But you're not wrong in your critique.

Good judgment comes from experience. Experience often comes from bad judgment.
The photo above, also a fair distance, is very low smoke, taking a real close look (doesn’t show ANY opposite smoke though because smoke still too low there, sorry). The camera is facing toward/into that smoke, camera facing basically SouthWest). Thanks for posting it.
The shear rate IMO is only very significant for just those few minutes around this tragic take-off. The smoke photo on Aviation Herald’s site (mentioned earlier in this thread), “from a distance”, facing mostly North, shows two nearly opposing directions; the 8:00z metar (8minutes prior) indicated surface reading was 7kts 20degrees off the beak closest to that take-off time (worked out to 6.58kts rwy-headwind). The opposing direction air above 200agl (aforementioned), ie the real hot dry air moving in from east/higher-ground … still requires some interpolation to prove accurately (indore/bhopal wx-hist/East .. 12mph/ene)
In the hour of this accident, just after high noon, the extreme hot dry air is moving in steady from ENE (along the north/ne side of an eastward moving low pressure centre situated well SE of VAAH ) … the hottest in India
in 2025 (118.4F).
A shear rate, is expressed in knots per 1000 feet. To compare with other shears one would have to multiply any potentially provable negative shear-numbers here by a factor of 5 (what ever they actually were in just these approx 200 feet above ground level of this aircraft).
