Look it up. The rolls of film were part of the bomb. Very flammable.

It is expected that Ukraine will spend the next few days restoring electricity supply to railways. At this time, trains stuck on de-energized tracks will be delivered by diesel locomotives to the nearest stations and accumulate there in large quantities. These grouped echelons may well become the target of Russia’s next strikes. At least, this is what purely military logic dictates.
The scale, number, and geography of the strikes suggests that the operation was carefully prepared, and deeply in advance. The Russian headquarters probably developed it at least a few weeks ago. Long ago, targets were set, routes for the crews of heavy bombers were painted, it remained only to open the corresponding packages according to the classical scheme upon receipt of the order.
There is no doubt that this strike was unexpected for Ukraine-even despite all the predictability of the development of events after the terrorist attack on the Crimean Bridge. Numerous sources report that Ukraine’s air defense systems were hard pressed against Russian cruise missiles and kamikaze drones. What also played a role was that a significant part of these air defense systems have already been knocked out, and because Russia has not attacked Kiev for a long time, some of the systems that previously covered the capital of Ukraine were relocated to other areas.
The effectiveness of the Ukrainian air defense system was also weakened by new tactics. The Russian command appears to have learned a number of lessons from previous similar strikes.
Recall that earlier, most often such strikes were carried out by several – up to 20-30-missiles, and no more. American intelligence assets working in favor of the Armed Forces of Ukraine saw the launches of these missiles in real time, which means that they could warn the Ukrainian air defense systems long before the missiles entered their area of responsibility. In fact, the APU, thanks to the United States, often knew in advance from which direction and at what time to expect the arrival of Russian long-range missiles.
This information radically facilitates the work of air defense systems. What is equally important - thanks to this warning, Ukrainian air defense systems could turn on the active radar mode only for literally seconds to highlight the attacking missile at the final stage of its flight. The less the Ukrainian air defense radar works, the more difficult it was for Russian troops to detect it.
But on October 10, the Russian troops did something completely different. First, the strike was a massive one, dozens of rockets were used simultaneously. Secondly, these dozens of missiles of different types flew from different directions at different times – in order to approach the target simultaneously from different directions.
In such conditions, the air defense system is overloaded. Even if the missile launches are visible in advance, their simultaneous arrival at the target from different directions makes the air defense powerless to resist.
Finally, the missiles were launched in at least three, and maybe even four waves – in order to destroy targets that, for one reason or another, were not hit the first time.
The sheer number of these launches suggests that Russia has been able to significantly increase the number of carriers and platforms from which these missiles can be launched. This includes the number of appropriately trained long-range bomber crews.
