From the article:

"Following the record run, a cell inside the pack became damaged and Chip
executed a "priority landing" with no power, at Inyokern's 7,100 foot long
runway 33."

You also have to go far.

Motor-Trend, Car of the Year is Electric:

Priced at a mere $49,900 to $97,900.

400wh/kg is achieved:

(They already know how to produce
1500wh/kg. It is forthcoming.)

Gasoline is 13,000 WH/kg; only an order of magnitude short.

Plane with built-in solar panels:

(Actually, the entire surface...both top and
bottom should be covered in photovoltaics)

For flying inverted?

On a clear day with your panels at 90 degrees to the Sun you get about
1 kW/square meter.

With the panels at 45 degrees to the Sun you get about 700 W/square meter.

Be sure to land well before dusk.
