Narrative:

I was training someone on west radar as aircraft X departed ska on the west climb; climbing to 050. Aircraft X checked on; and was radar identified. When the trainee was ready to turn aircraft X to the downwind; aircraft X did not respond. Aircraft X was not able to be reached for the next 20 miles. During that time; aircraft X entered a 059 MVA at 050. The trainee attempted to reach aircraft X on guard; on multiple frequencies; and through a company helicopter that was maneuvering in the area. Aircraft X was unable to be reached through any of these methods. Aircraft X eventually checked back on and said they had a 'comm' issue. I recommend a more extensive dialog and collaboration between ska and geg. It is important that aircraft departing ska have an understanding of how these situations can affect our workload. I believe controllers from both facilities and ska pilots would benefit from more inter-facility dialogs.

Title: GEG Controller reported KC135 departed; lost radios then entered subsequent higher Minimum Vectoring Altitude.

Narrative: I was training someone on West Radar as Aircraft X departed SKA on the West Climb; climbing to 050. Aircraft X checked on; and was radar identified. When the trainee was ready to turn Aircraft X to the downwind; Aircraft X did not respond. Aircraft X was not able to be reached for the next 20 miles. During that time; Aircraft X entered a 059 MVA at 050. The trainee attempted to reach Aircraft X on guard; on multiple frequencies; and through a company helicopter that was maneuvering in the area. Aircraft X was unable to be reached through any of these methods. Aircraft X eventually checked back on and said they had a 'comm' issue. I recommend a more extensive dialog and collaboration between SKA and GEG. It is important that aircraft departing SKA have an understanding of how these situations can affect our workload. I believe controllers from both facilities and SKA pilots would benefit from more inter-facility dialogs.
