The fact of the matter is when I opened a flight route from Moscow SVO via Cairo and Khartoum to Nairobi using a Tupolev 154 the System froze on the leg Khartoum to Nairobi, and I have as a result a profit of exactly 0 on this flight with 0 passengers but the route is shown. Please help this issue. As well as please introduce Tupolev 134 as it is such a mainstream important airliner of our time. Thank you.
