The circuit chiefs' fear results from last season's low viewership rates and they have invested much this year to ensure a better audience figure, the Mirror reports.
Worried that there will not be much audience to view the biggest motor sport event in June if Vettel keeps his winning streak alive this season, circuit president Derek Warwick has said that he yearned to see Hamilton and Button winning at Barcelona next weekend as he says that their victory would mean a lot to them.
Silverstone MD Richard Phillips said that if either Hamilton or Button or both the British drivers make it to the podium, then that will contribute enormously to the ticket sales, adding that people like to see a variety and are not there to look forward to the obvious victory of Red Bull racer Vettel, insisting that it will be good if Vettel does not win the crown each time.
The Silverstone authorities have focused on the crisis management this time by spending hugely on drainage, providing for over 4,000 extra parking spaces, an improved coach system, increased park and ride facilities and special trains running from London to Milton Keynes for the first time.
Last year's rain-ravaged grounds witnessed 2,97,000 people, including a record 1,47,000 race day attendance after the rain stopped, causing Silverstone to pay out one million euros in compensation.
While Vettel has won twice in four events, Hamilton has finished on the podium twice and predicted that he is on the verge of a victory breakthrough and Button, yet to finish higher than fifth, is relying on the British tournament to rescue his season, the report added.
