Anchorage center developmental reported an unsafe situation where they thought the aircraft was ok in relationship to its heading and altitude. Supervisor advised both controllers there was a problem and controllers reacted by climbing the aircraft and getting it back on course.

Narrative:
The r-side and myself were working a decently busy sector of 5 and 6 combined. We were working normal traffic along with military traffic. Aircraft X's strip printed and I observed the route was ted.v319.sqa.ZZZ at altitude 120. The aircraft at that altitude will work with the airway they would be on. I moved onto the next task and the sector started to get busy. Sometime later; the MSAW (minimum safe altitude warning) alert went off with reference to aircraft X. The r-side and I both looked and came to the conclusion he should be on the airway and there shouldn't be a problem because the aircraft was level at his assigned altitude. The area where the aircraft was; was very cluttered. The r-side came into agreement that it was false and that I would let our supervisor know about the issue. I called over the supervisor and he proceeded to look further and found that they were in fact not on the airway and were in a 137 mia (minimum IFR altitude). We immediately took action to correct the issue with turn controls to aircraft X. We had switch the aircraft to the next frequency just before the issue and lost coms with the aircraft. We were able to relay through an over flight aircraft and get the aircraft to contact us and turn to the south to leave the lower mia. Once the aircraft was clear and then given a route that would not impede an mia we asked the pilot what had happened.

Title: Anchorage Center Developmental reported an unsafe situation where they thought the aircraft was ok in relationship to its heading and altitude. Supervisor advised both Controllers there was a problem and Controllers reacted by climbing the aircraft and getting it back on course.
Narrative: The R-side and myself were working a decently busy sector of 5 and 6 combined. We were working normal traffic along with military traffic. Aircraft X's strip printed and I observed the route was TED.v319.SQA.ZZZ at altitude 120. The aircraft at that altitude will work with the airway they would be on. I moved onto the next task and the sector started to get busy. Sometime later; the MSAW (Minimum Safe Altitude Warning) alert went off with reference to Aircraft X. The R-side and I both looked and came to the conclusion he should be on the airway and there shouldn't be a problem because the aircraft was level at his assigned altitude.
