Was Spamair crash sabotage?

What if the Spamair crash was sabotage. The story we are given about the pilot returning from the takeoff due to a faulty temereature gauge seems a bit fishy. Perhaps they are not telling us all the truth. I know that the workers were on strick and the company laid off over 1000 workers. Whait if an angry mechanic did shoddy work, that too is a possibility.
