THE plane flown by billionaire Dan Petrescu burst into flames 16 seconds before hitting a building, it was reported.

The reasons for the single engine plane plummeting from the sky soon after taking off from Milan airport remain a mystery.

All eight people on board the aircraft were killed during the tragedy.

Petrescu, 68, was one of Romania's richest men and had been travelling with his son Dan Stefan Petrescu, 30, and his 65-year-old wife Regina Petrescu.

Witnesses said the plane burst into flames and made what investigators call a "vertical fall" 16 seconds before it hit the ground, Corriere della Serra reports.

The Pilatus PC-12 single engine plane took off from the main runway at Linate airport at 1.04pm local time.

It performed a right hand turn that would have taken it on its route to Olbia in Sardinia but instead of heading south it went towards the suburb of San Donato.

Frantic controllers asked the billionaire "why did you divert?" as the aircraft veered off course.

The plane was travelling at about 200mph when it slammed into the building in a fireball 11 minutes after take off.

Filippo Nascimbene, his wife Claire Alexandrescou, their one-year-old son Rafael, and her mother Miruna Anca Wanda Lozinschi, were all also killed in the tragedy, Rainews.it reports.

Dan Stefan Petrescu, the son who is supposed to have died in the crash as well, is a researcher in viral-based nanotechnology. https://wires.onlinelibrary.wiley.com/d ... /wnan.1508

Viral-based nanomaterials for plasmonic and photonic materials and devices by Dan Stefan Petrescu and Amy Zcuchmacher Blum:

Excerpt:

Over the last decade, viruses have established themselves as a powerful tool in nanotechnology. Their proteinaceous capsids benefit from biocompatibility, chemical addressability, and a variety of sizes and geometries, while their ability to encapsulate, scaffold, and self-assemble enables their use for a wide array of purposes. Moreover, the scaling up of viral-based nanotechnologies is facilitated by high capsid production yield and speed, which is particularly advantageous when compared with slower and costlier lithographic techniques. These features enable the bottom-up fabrication of photonic and plasmonic materials, which relies on the precise arrangement of photoactive material at the nanoscale to control phenomena such as electromagnetic wave propagation and energy transfer. The interdisciplinary approach required for the fabrication of such materials combines techniques from the life sciences and device engineering, thus promoting innovative research. Materials with applications spanning the fields of sensing (biological, chemical, and physical sensors), nanomedicine (cellular imaging, drug delivery, phototherapy), energy transfer and conversion (solar cells, light harvesting, photocatalysis), metamaterials (negative refraction, artificial magnetism, near-field amplification), and nanoparticle synthesis are considered with exclusive emphasis on viral capsids and protein cages.

Viral capsids and protein cages are becoming well-established nanotechnological tools for the fabrication of photonic and plasmonic materials and devices spanning fields such as sensing, nanomedicine, energy transfer and conversion, metamaterials, and nanoparticle synthesis.
