Jumbo's left its door open
But there's no need to panic.
It's just NASA's new flying telescope SOFIA - which is designed for infrared astronomy observations at altitudes of about 41,000 feet (about 12 km) in the stratosphere.
The water vapor in the Earth's atmosphere blocks some infrared wavelengths from reaching the ground, but SOFIA's flight capability allows it to rise above it all.
Engineers have been busy testing it out and expect to have the telescope up and running this year.
