What's this bright object flying at high speed over BKE?

Stomper Jonathan was driving along the Bukit Timah Expressway (BKE) on Tuesday morning (May 28) when he saw a bright object flying quickly overhead.

He was driving near Bukit Panjang and towards Changi Airport at around 6.30am when he saw it.

"Both my son and I briefly saw a bright blue light flash across the sky," he said.

"It didn't appear to be a plane or helicopter, a drone perhaps?

"I reviewed the video and it's not likely a drone as it didn't have any flashing LED lights.

"Did anyone else see this?"
