No, there's not a drama behind every peculiar event you may think you see. Late night arrivals into a quiet Gatwick, ATC frequently let you land on whichever runway you like. An apparent off schedule landing could just be a delayed flight, not an illness crisis! Strobes on at the gate may be the ground engineer checking the aeroplane for turnaround, not the pilots forgetting to turn them off, similarly flaps down at the gate may be maintenance or checking rather than pilots 'forgetting' to retract them. People never look for the mundane or boring with aviation- they always assume drama and crisis!
