You might be right. I was pretty sure that the ejection system was changed when they added the new zero/zero Zvezda 36 seats later on. I seem to remember that the Russians tested sequential ejection and the rockets burned the other pilot when done that way, so they switched to simultaneous ejection on both th SU24 and the 34. The 34, as far as I know, does not need the helpers to keep the elevators up keeping it from interfering with the stick and catch the ejection handle. The airframe on a SU34 is based on the SU 27 and had an all new and larger cockpit section installed.

Would you happen to know which Russian bomber planes have more than just one person in the crew?
