F1 testing day five: Stoffel Vandoorne and Lewis Hamilton both encountered problems
Felipe Massa can never be too old
Felipe Massa had probably barely taken his driving gloves off when the phone rang from Williams, asking him to return from retirement and replace Mercedes-bound Valtteri Bottas.
The 35-year-old Brazilian was only too happy to jump back in the Williams seat and after Lance Stroll's three offs ended their first week a day early, Massa impressed in the today racking up more than 150 laps and topping the timing sheets.
If engines turn out to be a crucial element in 2017, the Mercedes-powered Williams might have a thing or two to say.

Which F1 2017 car is the best-looking on the grid?
Pascal Wehrlein still has plenty to prove
After an ugly crash during the Race of Champions, an exhibition event in the US, Wehrlein was ruled out of the first week of testing with a neck injury.
But the Mercedes development driver, on loan at Sauber for the season, completed a trouble-free morning with 47 laps under his belt in the new car.
Nevertheless, Mercedes shunned him for Nico Rosberg's seat after failing to impress for Manor last year and will have to show proper pace in the Sauber to change opinions about him at Brackley.

James Allison is back
Technical chief James Allison left Ferrari last summer to spend more time with his family after the tragic death of his wife.
A well-liked and talented member of the pit wall, Allison took time away from the sport which requires so much travel and commitment.
But when he decided he wanted to come back to the sport, there was no shortage of offers for him.
With Paddy Lowe leaving, likely to take a position at Williams once his gardening leave is complete, Mercedes had a space and he was the perfect man to fill it.
Today, he was spotted roaming the pit-lane in Mercedes colours for the first time, and no-one could do anything else but wish him well.
From a technical perspective, he was the lead on the concept for the new Ferrari, which looks genuinely quick. It demonstrates that he might be the best signing of the winter anywhere on the grid as Mercedes continue to strengthen.

McLaren fans are back behind the sofa
Another day, another McLaren-Honda engine problem. This year marks 19 years since the Woking team last lifted the Constructors' title, then with a Mercedes engine, and how the fans must miss those days.
Best guesses suggest McLaren have already used six Honda engines in five days of testing, although the Japanese company themselves have denied it is as many as that. Either way, it is not promising and new boss Zak Brown's assertion that they "won't be winning any races in 2017" looks pretty spot on at present.
Lewis Hamilton and Mercedes aren't perfect
Lewis Hamilton had to end his morning sessions 30 minutes early because of some damage to the floor of Mercedes as they encountered their second serious problem of testing.
The defending champions have found life pretty easy so far in 2017 but Hamilton complained that he had to contend with dual problems with floor and tyre degradation in the warmest conditions so far.
The same driver was disappointed with the fact the tyres weren't degrading in colder temperatures last week, so it's difficult for Pirelli to win with Hamilton it would seem.
