I have just bought 767-300 and I am already disapointed because the plane is not complete: the jettison fuel is missing. I do not understand that a product seemingly so close to the reality does not offer a fuel Jettison panel. I am discovering the product. I hope to have no other unpleasant surprises...

Yes this is very sad CS release new product 767-200 ,The KC-767 Tanker,The E-767 AWACS, and non of this addons have jettison fuel switch I don't know why this was not sort it out in first update of 767-300 ,service pack and I also don't understand why jettison fuel is missing in 757 as well let's wait and see if this will be fix in next SP
