    Yes, I agree, above all because, afaik, on the Tu-22 the ejection system was only downward, so, below the 1,000 ft, it was impossible to eject safely and also with the aircraft on the belly, I don't know how they could escape from the fuselage. I think that a ground crew should raise the bomber with a crane and if the Tu-22 caught on fire??????

    Someone know why the ZIL-135 had two engines, each of which drove the four wheels of each side of the beast????? A very strage configuration for me: and if an engine broke?

    the BTR-60 had the same arrangement... ie two engines each driving the set of four wheels on each side.

    from memory it used a cheaper less powerful engine by using two and with one engine driving one sides wheels it meant when turning it didn't need a diferential to stop the outer wheels skidding. (ie when turning the outer wheels cover more ground than the inner wheels... if they are both powered by one engine with no differential then one set will skid and lose traction.)

    It makes it more complicated but allows some components to be simplified and less powerful engines can be used which are cheaper.

    But therefore the Zil-135 or the BTR60 could run also with a single engine only and with the wheels of one side only???

    From memory, on BTR-60, the engine on the right propels the second and fourth axles and the left one the first and third axles. Each axles have it's own differential.
    Each engines can works if the other is disabled (combat related or not) and the vehicle can move, albeit with reduced speed.

    But therefore the Zil-135 or the BTR60 could run also with a single engine only and with the wheels of one side only???

    they were pretty much connected via shafts so if an engine failed the other could propel the vehicle... but it would be like a single engine vehicle with cylinders not firing properly... ie greatly reduced power.

    the complex arrangement on the BTR was to make the vehicles cheaper... not simpler.

    By using a smaller less powerful engine widely used in trucks of the period they saved money and time... which are both critical when trying to get troops out of trucks and into armoured amphibious vehicles.

    From memory the BTR-70 also had two engines, but they were diesels of greater power, better fuel economy... and reduced fire risk... it was the BTR-80 that introduced a more powerful single engine diesel arrangement that simplified its design.

    (note add to the BTRs complex gearing system a system of centralised tire pressure regulation system and the BTRs would keep you busy in terms of maintainence... but mobility was considered very good.)
